On the magnetization process of ferromagnetic materials
The present article concludes that a ferromagnetic sample could be considered like a paramagnetic system where the role of magnetic moments plays magnetic domains. Based on this conclusion and taking into account presence of an anisotropic field the formula which describes magnetization dependence on the external magnetic field is derived. Expressions for a remanent magnetization and a coercive force are presented. The new parameter to characterize a magnetic stiffness of a material is introduced. A physical expression for a dynamic magnetic susceptibility as a function of material's characteristics, external magnetic field, and a temperature is given.
