英文摘要
In this research, we tried fabricating novel spintronic devices using ferromagnets/diamond semiconductors heterostructures and obtained mainly following three results.(1) It is found that ferromagnetic and half-metallic Heusler Co_2MnSi can be epitaxially grown on diamond for the first time.(2) Schottky barrier heights between ferromagnetic metal and diamond semiconductor can be controlled by selecting ferromagnetic metals with proper work function.(3) Signals related to spin injection were observed by 3-probe Hanle measurements using Ni/diamond ferromagnetic heterojunctions(τ=~20ps).
