Certain new aspects of rotational switching in polycrystalline bulk ferromagnetics

The rotational switching process is analyzed on the basis of this author´s equation of motion, in which the damping term is directly related to magnetic diffusion aftereffect. Some experimental results are presented which are pertinent to temperature characteristics of material parameters for Mn-Mg-Zn ferrite. Calculations of the damping factor in the Gilbert equation are made, starting from experimental data for displacement model of magnetization. A discussion is carried out on the validity of displacement and rotational models of magnetization.
