Title :Magnetostatic Wave Propagation over Different Bias Magnetic Field
Authors :Satoshi YAKATA
Issue Date :21-Apr-2020
Abstract :The propagation of magnetostatic wave in ferromagnetic material was investigated using micromagnetic simulation. In ferromagnetic medium, magnetostatic wave excited by rf magnetic field and the propagation over different internal magnetic field was observed. It is found that magnetostatic wave partially penetrated through the boundary between the regions which has different magnetic field. After penetration, the amplitude reduced significantly, and the wavelength increased depend on difference of magnetic field strength. The mechanism can be explained by dispersion relation of magnetostatic wave in ferromagnetic material. It is also exhibited application of exchange bias field by attaching anti-ferromagnetic material, Ir25Mn75 on Ni80Fe20 ferromagnetic medium.
