Abstract

Numerical methods in the MuMAX3 software are used to calculate both the saturation fields and the resonance spectra of magnetization for a thin magnetic plate with perpendicular magnetic anisotropy. The optimal parameters for modeling autoresonance processes in yttrium iron garnet films are determined. The role of surface anisotropy and dipole-dipole interaction in modeling of static and dynamic magnetization in YIG film is discussed.

Численное моделирование поведения намагниченности в одноосных магнитных пленках

Численными методами в среде MuMAX3 проведен расчет полей насыщения и спектров резонансных частот намагниченности для тонкой магнитной пластины с анизотропией типа выделенная ось. Определены оптимальные параметры для моделирования авторезонансных процессов в пленках железоиттриевого граната. Изучена роль поверхностной анизотропии и диполь-дипольного взаимодействия в моделировании статической и динамической намагниченности в пленке.
