Published Papers

• Refereed, MATERIALS TRANSACTIONS, JAPAN INST METALS, Effect of Aging and Stress on Stability of beta Phase in Au-Cd-Ag, Yuki Matsuoka; Mao Fujita, Au52.5-xCd47.5Agx has a single beta phase in the composition range of x <= 41 and a wide temperature range extending to room temperature or below. Coexistence of the beta and alpha phases has been observed for 41 < x < 47, and the coexistence of the beta, alpha, and zeta phases has been observed for x >= 47, as thermal equilibrium states. We found that the alpha phase appears and coexists with the beta phase for x <= 41 in the aged alloy at room temperature. The mole fraction and the stability of the alpha phase depend on the atomic order of the beta phase. Moreover, it was found that the zeta phase is stress induced in the composition range of x <= 41. The zeta phase disappears with heat treatment to release strain, and so this zeta phase is not stable., May 2016, 57, 5, 624, 626, Scientific journal, 10.2320/matertrans.MB201514

• Refereed, MATERIALS TODAY-PROCEEDINGS, ELSEVIER SCIENCE BV, Composition dependence of the phase stability in Au-Cd-Ag martensitic alloy, Y. Matsuoka; M. Fujita; A. Nagahara, Au(52.5-)x-Cd-47.5-Ag-x noble metal alloy undergoes martensitic transformation and shows complex Ag dependence on transformation temperature. As Ag composition ratio increases, beta- and alpha- coexistence phase appears. The behavior of this Ag-rich region was studied. Atoms of the beta-phase arrange disorderly (A2) in this region. The transformation temperature T-0 rises drastically and the magnitude of orthorhombic distortion becomes larger in comparison with that of adjoined beta-single phase. This result suggests a correlation between the orthorhombic distortion and T0. Excessively high packing fraction of the alpha-phase, atomic disorder in the beta-phase and small volume ratio of martensite / beta-phase makes the beta-phase unstable and stimulates transformation.

Au52.5-xCd47.5Agx has coexistent phase of beta-phase and alpha-phase of fcc structure at x > 42 at.%. The transformation temperature To decreases as Au is substituted on Ag over phase boundary. To increases by quench in both case of bulk and powder. This behavior is investigated that disordering of atoms and lattice defects make beta-phase (L2(1), B2 or bcc) unstable. Size effect was also inspected. Downsizing sample decreased the transformation temperature in beta-phase. On the contrary, the transformation temperature of the coexistent phase showed a tendency of increase. Downsizing is supposed to make difficult nucleation for martensitic transformation because of reduction of beta-phase ordered volume. Increasing of surface (disorder structure) ratio by downsizing of powder sample is estimated to make easy to transform from unstable beta-phase to martensite phase. (C) 2012 Elsevier B.V.

• Not Refereed, PROGRESS OF THEORETICAL PHYSICS SUPPLEMENT, PROGRESS THEORETICAL PHYSICS PUBLICATION OFFICE, Neutron diffraction investigation of the metamagnetic transition in Y2Cu2O5, B Lebech; Y Matsuoka; K Kakurai; M Motokawa, Y2Cu2O5 shows two successive metamagnetic transitions for magnetic fields (B) parallel to the b-axis, one at B-c1 similar to 2.8 T and one at B-c2 similar or equal to 4.7 T. Above B-c2 the magnetisation gradually increases and saturates at B-S similar to 7.3 T. Generally such metamagnetic transitions are not expected in a Cu2+ spin system because of the small anisotropy and hence have never before been observed in this type of compounds. We performed neutron diffraction experiments in zero and applied fields parallel to the b-axis to shed some light on the nature of these metamagnetic transitions. An unexpected magnetic structure with tripling of the unit cell in the b-direction has been observed for applied fields of B-cl < B < B-c2. The possible magnetic structures compatible with the crystal structure symmetry have been determined by means of symmetry analysis and these results are compared to the neutron diffraction and magnetisation data., 2005, 159, 159, 222, 227, Scientific journal, 10.1143/PTPS.159.222

• Refereed, JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS, ELSEVIER SCIENCE BV, Neutron scattering study of linear-chain Haldane compounds NDMAZ and NDMAP, N Metoki; Y Koike; Y Matsuoka; T Kobayashi; M Yamashita, Neutron scattering experiments were carried out for the new Haldane compounds Ni(C5H14N2)(2)N-3(ClO4) (NDMAZ) and Ni(C5H14N2)(2)N-3(PF6) (NDMAP) in the magnetic field up to 10 T in order to investigate the field-induced long-range ordering and the spin excitation. For NDMAZ. the triplet excited state (1.61, 1.76, and 3.2 meV) and field dependence of these levels were observed at Q = (000.5). From these data. the intra-chain coupling constant approximate to 4.3 meV and the anisotropic parameters D approximate to 0.76 meV and /E/ approximate to 0.038 meV were estimated. For NDMAP the gap was observed at about 0.48 and 0.64 meV at Q (000.5). By applying the field of 5 T, the first excited state shifted below the resolution less than 0.13 meV. Above the critical field H-C, the intensities of singlet-triplet excitation becomes very weak. This work is the first neutron scattering study on a Haldane system above the critical fields.

We have carried out neutron diffraction measurements of a Heusler-type off-stoichiometric Ni2.19Mn0.81Ga alloy under the magnetic field of up to 5T using the HERMES and the TAS-2 diffractometers both installed at the JRR-3M reactor of Japan Atomic Energy Research Institute (JAERI). This alloy has the martensitic transformation temperature (M-S point) of about 350 K. which coincides with the magnetic Curie temperature (T-C). It is ferromagnetic in the martensitic phase and paramagnetic in the cubic Heusler phase. By Rietveld analysis of the diffraction patterns we have confirmed that the martensitic phase and the cubic phase coexist at 350 K. We have also discovered that half of the cubic phase changes to martensitic phase under the magnetic field of 5T at this temperature. This finding indicates the possibility of controlling the martensitic transformation by means of the external magnetic field., Nov. 2000, 69, 11, 3485, 3488, Scientific journal, 10.1143/JPSJ.69.3485

• Not Refereed, INTERNATIONAL JOURNAL OF APPLIED ELECTROMAGNETICS AND MECHANICS, IOS PRESS, Possibility of controlling the shape memory effect by magnetic field, K Inoue; K Enami; M Igawa; Y Yamaguchi; K Ohoyama; Y Morii; Y Matsuoka; K Inoue, We have made the Heusler-type Ni2MnGa-based alloys, Ni2.18Mn0.82Ga, Ni2.19Mn0.81Ga and Ni2Mn0.92Ga1.08, which have the martensitic transformation temperature coincident with the Curie temperature. The powder neutron diffraction measurements of these alloys were performed. The Rietveld analysis of the diffraction patterns showed that at least two crystal structures coexist in each martensitic phase. For Ni2.18Mn0.82Ga and Ni2.19Mn0.81Ga, the main structure is a monoclinic one with a six-layers shuffling and a small amount of orthorhombic structure distorted from the cubic Heusler one is included. For Ni2Mn0.92Ga1.08, the main structure is tetragonal whereas a small amount of other structures seem to be included. The neutron diffraction of Ni2.19Mn0.81Ga under magnetic field up to 5 T at the coincident transformation temperature of 350 K shows that the magnetic field causes the phase transformation from cubic phase to martensitic one. The result suggests the possibility of controlling the shape memory effect originating from the thermoelastic martensitic transformation, by applying the external magnetic field instead of changing the temperature., 2000, 12, 1-2, 25, 33, Scientific journal

• Refereed, MATERIALS TRANSACTIONS JIM, JAPAN INST METALS, Effects of static magnetic field and hydrostatic pressure on the isothermal martensitic transformation in an Fe-Ni-Cr alloy, T Kakeshita; Y Sato; T Saburi; K Shimizu; Y Matsuoka; K Kindo; S Endo, The effects of static magnetic field and hydrostatic pressure on the isothermal martensitic transformation, whose nose temperature is about 143 K, in an Fe-25.0Ni-4.0Cr alloy (mass%) have been studied by examining the TTT diagrams under those external fields. The static magnetic field makes the nose temperature lower and the incubation time shorter than those under no external magnetic field, while the hydrostatic pressure makes the nose temperature higher and the incubation time longer than those under no external hydrostatic pressure. The shifts of nose temperature and incubation time increase with increasing the strength of those external fields. These results are quite similar to those of a previous Fe-Ni-Mn alloy exhibiting an isothermal martensitic transformation and are well explained by the phenomenological theory previously constructed by the present authors, which gives a unified explanation for the isothermal and athermal processes of martensitic transformations., Feb. 1999, 40, 2, 107, 111, Scientific journal, 10.2320/matertrans1989.40.107

• Not Refereed, MATERIALS TRANSACTIONS JIM, JAPAN INST METALS, Effects of magnetic field on athermal and isothermal martensitic transformations in Fe-Ni-Cr alloys, T Kakeshita; Y Sato; T Saburi; K Shimizu; Y Matsuoka; K Kindo, Effects of magnetic field on the athermal martensitic transformation in an Fe-31.4Ni-0.5Cr alloy (mass%), whose M-s temperature is about 183 K, and on the isothermal one in an Fe-25.0Ni-4.0Cr alloy (mass%), whose nose temperature is about 143 K, have been examined by measuring magnetic field susceptibility and magnetization, and by observing optical microstructure, applying pulsed high magnetic fields up to 31 MA/m. The obtained results were the following: The austenitic state in the Fe-31.4Ni-0.5Cr alloy is ferromagnetic, whereas that in the Fe-25.0Ni-4.0Cr alloy is spin glass. Even in the latter alloy, martensitic transformation is induced instantaneously under pulsed magnetic fields higher than a critical one over a wide temperature range, as in the former alloy. This result suggests that the originally isothermal process of martensitic transformation changes to the athermal one under high magnetic fields. Optical microscopy showed that isothermal martensite plates of the Fe-25.0Ni-4.0Cr alloy under no magnetic field grow gradually during isothermal holding. Moreover, morphology of the magnetic field-induced martensites of both alloys was almost the same as that of thermally-induced ones, irrespective of the formation temperature. A thermodynamic calculation for the critical magnetic field vs temperature relation has been done for both the alloys by using an equation previously proposed, and the calculated relations are all in good agreement with the experimental ones in the wide temperature range examined. The present results are almost the same as those in the study previously examined on the athermal and isothermal martensitic transformations in Fe-Ni-Mn alloys under pulsed high magnetic fields., Feb. 1999, 40, 2, 100, 106, Scientific journal, 10.2320/matertrans1989.40.100

At H = 0, the determined magnetic structure is identical with that obtained for the powder sample, but new diffraction peaks appear at completely unexpected positions between H-c1 and H-c2, which means a three-lattice period modulation along the b-axis but this structure change is mysterious from the crystallographic point of view.

At field strengths far above the spin-flop field our data are consistent with predictions for the n = 2 chiral universality class, beta = 0.25. Close to the spin-flop transition, where the weak Ising anisotropy present in CsNiCl3 is cancelled by the magnetic field, good agreement is achieved with the critical exponent of the n = 3 chiral universality class., Jun. 1997, 234, 554, 556, Scientific journal, 10.1016/S0921-4526(96)01176-3

• Refereed, JAPANESE JOURNAL OF APPLIED PHYSICS PART 1-REGULAR PAPERS SHORT NOTES & REVIEW PAPERS, JAPAN J APPLIED PHYSICS, Electron paramagnetic resonance and Mossbauer spectra of iron ions in Bizen pottery, Y Matsuoka; M Ikeya, Electron paramagnetic resonance (EPR) and Mossbauer spectra of Japanese traditional Bizen pottery and its constituent clays have been measured to study the relationship between the color of pottery surface and the relevant states of iron ions (Fe3+ and Fe2+). Hyperfine signals of Mn2+, presumably in carbonates, and a broad signal at g = 2.0 similar to that of hematite (Fe2O3) were observed for good-quality clay, while a signal at g > 9 similar to that of magnetite (Fe3O4) was observed for poor-quality clay. In pottery, the apparent g-factor of g = 4.3 due to the apparent g-factor of g = 4.3 due to a large orthorhombic distortion E (S-x(2)-S-y(2)) and g = 6 due to a large axial field DSz2 were observed in addition to the broad signal around g = 2 due to oxidation of iron into Fe2O3. Subtle change of colors resulted in the change of EPR spectra. Mossbauer spectra indicated that almost all of the iron ions at the surface of pottery are strongly oxidized into Fe3+ when the pottery is fired in oxidizing atmosphere, while those inside the pottery and at the surface fired at reducing atmosphere are not strongly oxidized into Fe3+., Nov. 1995, 34, 11, 6068, 6072, Scientific journal, 10.1143/JJAP.34.6068

Several new platinum complexes containing substituted bipyridine ligands, [PtX_2(R_2bpy)] (X=Cl^-, CN^-, R=(CH_2)_nCH_3 [n= 6-10], COOH) have been synthesized in order to control nano-structures sophisticatedly. [Pt(CN)_2(dnbpy)] (dnbpy=4,4'-dinonyl-2,2'-bipyridine) exhibited vapochromic behavior in the solid states and sensitive concentration dependence of luminescence in solution. For the complex containing carboxyl groups, pH-dependent chromism was found. The X-ray analysis revealed that three-dimensional network structure having large cavities was constructed with hydrogen bonds and Pt-Pt interactions. The relationship between the network structural change and the chromism was discussed. 2) The Mechanism of the Vapochromic Behavior of a Dinuclear Bipyridine-platinum(ll) Complex. The dinuclear platinum(II) complex, syn-[Pt_2(pyt)_2(bpy)_2](PF_6)_2 (pyt=pyridine-2-thiolate ion, bpy=2,2'-bipyridine) exhibits a remarkable change in its luminescence by sensing organic vapors. Mechanistic studies of the vapochromism have been carried out on the basis of the structural and spectroscopic investigations of related complexes. It is suggested that the head-to-head arrangement of the syn isomer is essential to the vapochromic behavior., kaken
