Abstract :
The hysteresis in anisotropic Sr ferrite grains and Ba ferrite particles is described by statistical magnetization reversal behavior using phenomenological parameters. Consequently, these parameters are related to spontaneous magnetization, anisotropy, and microstructure geometry, using dimensionless microscopic constants.
