Abstract

For polycrystalline ferrites in the frequency range of large amplitude dispersion of complex initial magnetic permeability (known also as domain wall resonance/relaxation region) approximating relations for frequency dependence of magnetic loss tangent are proposed. The distinctive feature of approaches is the use of only several basic parameters of the ferrites: the static magnetic permeability, the saturation magnetization, and, in more general cases, the parameter that is related with grain size distribution scattering.
