Research Abstract

1.CeB_6の四重極モーメントの秩序の研究が椎名・酒井・斯波によってなされ、磁場中において八重極モーメントが誘起され、それによって長年の懸案であった中性子とNMRの不一致が解消することが示された。四重極ゆらぎについては倉本が研究した。Laの希釈系の実験の進展と合わせ、今後の発展が期待できる。
2.重い電子超伝導体UP_<t3>の超伝導の秩序パラメーターと超伝導機構
実験グループの北岡ら(阪大)によってUP_<t3>の温度-磁場相図が決められ、町田と大見により三重項超伝導による解釈が提出された。スピン軌道相互作用の大きさの評価などが今後の課題である。
3.Uを希薄に不純物として含む系の近藤効果の理論的研究が酒井・清水・三宅によってなされた。
特に、非フェルミ流体の性格について、物理量の計算が酒井・清水によりなされ、鋼塚ら(北大)の実験結果の説明が可能になった。
4.f電子系のバンド理論に関して軌道電流をとり入れる定式化が長谷川によってなされた。今後の発展が期待される。また、播磨がYb_4A_<S3>などの物質の電子状態について興味ある結果をえた。
