The observation of Skyrmion at room temperature were investigated using ferromagnetic thin films with perpendicular magnetic anisotropy. (1) In the experimental research using Co/Ni multilayer films, it observed the movement of the magnetic domain structures in magnetic wires, however it did not observed the Skyrmions. (2) In the research using numerical simulations, we investigated the nucleation and annihilation conditions of Skyrmions in Co / Ni multilayers and clarified the conditions that the Skyrmion exists stably at room temperature.
As other research, we investigated that (3) the magnitude of the topological Hall effect depending on the magnetization structure in the cross-shaped magnetic wire, and that (4) the changing the magnetic domain structures in the Ni wire on the piezoelectric substrate LiNbO3.
