Outline of Final Research Achievements |
In this research project, I have aimed at the development of next-generation spintronics devices and created magnetic layered compounds and their nanosheets. Regarding layered double hydroxides (LDH) containing magnetic ions, I have found out the following phenomena: (i) the negative magnetic exchange coupling interaction by integrating the different LDHs, and (ii) the photomodulation of magnetic properties by integrating with semiconductor nanosheets. Regarding transition metal tricalcogenides containing magnetic ions, I have found out the following strategies are effective: (i) long-term calcination with a gentle temperature gradient during synthesis, and (ii) ultrasonication in a polar solvent containing a base during exfoliation.

Academic Significance and Societal Importance of the Research Achievements |
本研究課題においては、「無機ナノシートが真に次世代エレクトロニクスを支える基幹物質となりうるか」を命題に掲げ、未解明な部分が多い無機ナノシートの磁気物性の開拓に焦点を当てた。 異なる物性を有する磁性層状複水酸化物ナノシートを巧妙に組み合わせることによって、単体では発現しない磁気物性を発現させることに成功したことは学術的にも社会 (産業) 的にも意義深いと言える。 また、スピントロニクス分野への応用に資する磁性リントリカルコゲナイドナノシートの合成に対する重要な知見を得たことは、今後の学際領域研究の発展に対して寄与するところが少なくないと言える。
