| Outline of Final Research Achievements |
The formation technologies of epitaxial thin films of RT5 ordered alloys consisting of rare-earth (R) and transition (T) metals are developed. The crystallization of RT5 ordered phase is promoted by employing an R or T element with lower melting point. Furthermore, the ordered phase formation is enhanced by partially substituting T site with Cu atom. The present study clarifies the formation conditions of hard magnetic RT5 alloy epitaxial films.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により、RT5合金膜のRおよびTサイトの元素選択に関する課題が明確となった。そして、元素選択および多元化により結晶性が優れたRT5合金膜の形成可能性が増大することが示され、それに伴い、構造および磁気特性の制御範囲の更なる拡張も期待される。本研究の技術は、硬磁性RT5合金膜の形成基本技術として高い可能性を持つと考えられる。
