报告题目：A micromagnetic simulation package based on COMSOL Multiphysics

报告摘要：Micromagnetic simulation is a numerical method widely used in studying magnetization dynamics and spin wave by treating the magnetization as a semi-classical quantity with coarse grain average in space. We developed a micromagnetic simulation package based on the widely used simulation app COMSOL Multiphysics. This new micromagnetic simulation tool can efficiently compute magnetization dynamics in several different types scenarios, including i) the static magnetization profile stabilization such as magnetic domain walls, magnetic skyrmions , ii) computing in time domain for the spin wave behavior excitation and propagation, and the dynamics of magnetic textures such as the magnetic domain wall or skyrmion motion, iii) computing in frequency domain for spin wave dispersion in trivial or non-trivial magnetic textures, and more importantly, iv) coupled to other physical fields such as the electromagnetic fields, thermal fields, mechanical fields that have already been embedded in COMSOL.
