Outline of Annual Research Achievements |
強相関多極子物質の物質開発と電子状態計算を行い,以下の結果を得た。 (1) 5d遷移金属Irを含む新規超伝導体Mg2Ir3Si (Tc = 7 K), Li2IrSi2 (3.3 K), SrIr2 (5.9 K) を開発した。(2) スピン軌道型モット絶縁体Sr2IrO4に対してトポケミカル反応によるフッ素化処理を適用することで,F層が挿入されたSr2Ir(O,F)6-dの合成に成功した。(3) PrMgNi4が非磁性基底二重項を持つ四極子活性な新たな系であることを,非弾性中性子散乱により明らかにした。(4) 4f2希薄系Y(Pr)Ir2Zn20の熱膨張および磁歪から,四極子に起因した量子臨界点の存在が示唆された。(5) 4f3系の物質開発を進め,NdCo2Zn20がクラマース基底二重項を持つことを非弾性中性子散乱実験から明らかにした。(6) La2O2Bi3Ag0.6Sn0.4S5.7Se0.3などの新超伝導体を開発し,BiS2系においても多層の伝導層を持つ物質が存在することを明らかにした。(7) 高エントロピー合金効果によりBiS2系の局所構造が制御可能であることを示し,この効果を用いた物質開発を進めた。(8)f電子系スキルミオン物質EuPtSiのフェルミ面を計算し実験結果と比較することで,その特徴を明らかにした。これはRKKY相互作用として現れるジャロシンスキー守谷項の解明につながる。(9) 新奇重い電子系超伝導体UTe2の電子構造計算を行い,常伝導状態の金属的性質の起源を議論した。(10) 実験グループと協力して,EuAu5, Mn2P, Ti2Sn3, UPt5などのフェルミ面を明らかにした。具体的な物質について電子構造計算に基づいたp-f混成効果を求めて,軌道近藤効果の発現条件について議論した。
