Outline of Final Research Achievements

We developed elemental technologies toward huge tunnel magnetoresistance (TMR) by focusing on interface states at half-metallic Heusler alloys and an MgAl2O4 barrier. (1) We found a promising interface layer material, FeAl alloys, through solid-state Al atomic diffusion effect observed at an ultrathin Al-containing alloy layer and a barrier. (2) By using MgAl2O4 barriers, perfectly lattice-matched interfaces with Heusler alloys were achieved. Additionally, a very high quality Heusler alloy layer was successfully grown on the MgAl2O4 barrier. (3) Advanced first-principles-based transport calculation methods have been developed. Especially, the calculations revealed excellent bias voltage dependence of TMR in an MgAl2O4 barrier MTJ, and a large exchange stiffness constant in Co-terminated CoFe, which is one of the most important factors for observing large TMR ratio at room temperature.

Academic Significance and Societal Importance of the Research Achievements

本課題期間内では当初狙っていたTMR比の更新までは到達しなかったが、実現に向けた幅広い重要なMTJの要素技術確立が達成されたと考えられる。特に原子レベル固相拡散現象が高度な界面構造の作製に有効利用できることが見いだされ、これは新しいMTJ設計指針を与えるものである。また、MgAl2O4をバリアとして用いることの優位性が明確になった。当初予定していなかった多結晶素子化の技術も確立され、実用素子への急速な展開へも期待されることから磁気メモリー、磁気センサーへの活用にもつながると期待される。理論計算技術の向上もめざましく、幅広い観点からMTJの解析が可能になったことの学術的意義は大きい。
