| Outline of Final Research Achievements |
In fields of spintronics, ferromagnetic semiconductors are required to fulfill both high Curie temperature and large magnetization. However, such requirement has not been satisfied yet. In this study, we discovered high temperature ferromagnetic semiconductor with large magnetization, which is not diluted ferromagnetic semiconductor. In addition, we discovered various rare earth monoxides such as ferromagnetic metal, highly conducting semiconductors, and superconductor. Their simple rocksalt structure enables to fabricate their heteroepitaxial structures. This achievement paves the way to spintronics using electrically conducting rare earth oxides.
