Research Abstract

5f電子を持つアクチノイド(An)系の多様な低次元の層状化合物、例えば、トリウム(Th), ウラン(U), ネプツ二ウム(Np)などの窒化塩化物AnNCl、錯体、カルコゲナイド(硫化物)、プニクタイト(リン化物)、酸化物、金属間化合物などを対象に、物質創製と、5f電子特有の低次元構造に由来する新規な電子物性(磁性、電気伝導性、超伝導など)を探索、両者の相関を明らかにする研究に取り組んだ。窒化ハロゲン化物研究では、UNClがキュウリー温度T_C=32Kの強磁性体であり、Li挿入によりネール温度T_N=180Kまでの反強磁性体へと変化することを明らかにした。特異な陽イオン-陽イオン結合を持つネプツニル錯体研究では、対応するランタノイド(4f電子系)のツリウム(Tm)錯体を含め、その特異な分子磁性挙動を、構造の次元性(0、1、2次元)との関連で系統的に明らかにし、未開拓のアクチノイド分子磁性研究に大きな進展をもたらした。同時に、Np化合物研究の有力な武器である^<237>Npメスバウアー分光測定法の開発・整備を大きく前進させた。またNpPd5Al_2単結晶を育成しこれがNp 系で世界初の重い電子系超伝導体であるここを発見するとともに、U硫化物がAn系ではきわめて稀有な大きな磁気抵抗効果を示すことを見出した。
