Outline of Final Research Achievements

We have found an excellent material for the thermal spin injection and developed an innovative wireless spin injection technique based on the efficient thermal spin injeciton with the ferromagnetic resonance. We have also demonstrated that a laterally configured resistive switching nano device and clarified the switching mechanism, In addition, we investigate the spin trasnport on a magnetic insulator and found that the magnetic insulator is a strong spin absorber. We believe that these findings open the avenue for the efficient control of material property using spin current.
