Outline of Annual Research Achievements

本研究では，主としてコバルトなどの3d遷移金属を含む化合物の純良単結晶育成，磁性および電子輸送特性とフェルミ面の性質を明らかにすることを目的として 研究を行っている.これまでに，FeSnとFeSn2および関連物質のCoSnについても純良単結晶育成し，電気抵抗率，磁化率および磁化測定を行いその物性を明らかにしてきた.また，ドハース・ファンアルフェン効果の測定を行いそれらのフェルミ面がバンド計算結果でよく説明されることを報告した.
本年度はこれらの化合物とともにFe2PおよびMn2Pの遷移金属化合についても研究を行った．Mn2Pについては，ドハース・ファンアルフェン効果の測定を行いそのフェルミ面の性質を明らかにし，学会で発表し論文にまとめた．さらに，最近4f電子系のスキルミオン化合物として注目されているEuPtSiや遷移金属T(=Cu, Rh)を含む希土類金属Euとの化合物EuT2Ge(Si)2，EuSnP, EuCuPやSn4P3, Ti2Sn3等についても研究を行った．それらの化合物の単結晶育成を行い，電気抵抗率，磁化率， 磁化，比熱等の測定を行い物性を明らかにしてきた.純良な単結晶が得られた化合物については，ドハース・ファンアルフェンス効果を測定しフェルミ面の性質を明らかにした．また，これの化合物のいくつかについては，量子臨界点近傍の物性を明らかにすることを目的にピストンシリンダーおよびキュービックア ンビルセルを用いて高圧力下の電気抵抗測定を行った.
これらの成果は，以下で示すように学会発表を行い論文にまとめて報告した.

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

前年度に引き続き研究を行ったFeSnおよびFeSn2に加え，MnP，Fe2PおよびMn2Pについて研究を行いその成果を学会発表を行いまた論文としてまとめて報告した.また，EuT2Ge(Si)2(T: 遷移金属)およびウルマナイト化合物EuPtSiについても電気抵抗率，磁化率，比熱，およびドハース・ファンアルフェン効果の測定を行いその物性を明らかにし学会および論文発表を行った.さらに，結晶反転対称性のないEuTGe(Si)3についても単結晶試料の育成を行ったところである.これから詳細を明らかする予定である.

Strategy for Future Research Activity

これまで研究を行ってきた結晶反転対称性を持たない結晶構造の遷移金属化合物のフェルミ面を明らかにするため純良単結晶を育成しその物性を明らかにする.今年度は，遷移金属化合物に加え反転対称性をもたないラッシュバ型EuTGe(Si)3(T: 遷移金属)についての研究を進めたい．特に，多重磁気転移の存在が知られているがその詳細が明らかになっていないEuNiSi3の物性を中心に研究を行う．また，この化合物の量子臨界点近傍の物性を明らかにするために圧力下の物性測定もあわせて行いたい．

Causes of Carryover

理由: 実験装置の改良があまり進展していない．実験用寒剤の使用が予定より少なかった．
使用予定: 次年度は寒剤の使用が増える予定である．また，実験用試料作成で原料の購入を予定している．実験装置の改良を計画しておりその部品の購入も必要である．
