| Outline of Final Research Achievements |
In this research project, to make a breakthrough in realizing spintronics as a practical electronics, we carried out collaborative research between computational design for spintronics and experimental verification. Concerning to the design for semiconductor spintronics, it is proposed that the ‘co-doping’ method and the spinodal decomposition can be used to control the ferromagnetism of dilute magnetic semiconductors (DMS). We also proposed new DMS systems including GeTe-DMS and so on.
The magnetic anisotropy energy (MAE) was also studied, particularly for the metallic thin film (vacuum/M/Fe/M(001), M=Pt, Pd), the magnetic junction film (MgO/Fe/M(001), M=Au.Pt), and double interface thin film (MgO/Fe/MgO) were investigated. Experimental demonstrations were performed concerning to the computational design for metallic spintronics, especially for the voltage control of magnetic anisotropy, and the semi-quantitative agreement with the experimental data was obtained.
