Outline of Final Research Achievements |
The high quality single crystals of the Co compounds and the related compounds, whose magnetic sates are very sensitive to the external and internal environmental parameters were grown and measured the electrical resistivity and thermopower under high magnetic field or the high pressure, specific heat, and de Haas-van Alphen effect in order to clarify their magnetic and transport properties, and the Fermi surface properties. We have studied the tetragonal ThCr2Si2 type SrCo2P2 and related EuCo2P2 and LaCo2P2 compounds, a substitution system of the pyrite compound Co(S,Se)2 revealing meta-transition, the tetragonal BaNiSn3-type EuTX3 (T: transition metal, X: Si, Ge, P) and the cubic Ullmannite-type EuPtSi(Ge) without crystal inversion symmetry.

Academic Significance and Societal Importance of the Research Achievements |
遷移金属コバルトCoおよび希土類金属ユーロピウムEuの金属間化合物で,磁気的に不安定あるいは幾何学的フラストレーション状態にある物質の性質を明らかにした.局在モーメントのスキルミオン相の存在が明らかになったEuPtSiについては今後の研究の進展が期待できる.
