Abstract

The longitudinal magnetic susceptibility of a ferromagnetic with an easy axis of magnetization, and whose composition includes ferromagnetic spherical inclusions with other physical properties, is calculated using a quasi-classical kinetic equation for the magnon distribution function. The axes of anisotropy of a statistical ensemble of ferromagnetic nanoparticles are directed randomly. It is shown that the properties of these substances depend strongly on the concentration of nanoparticles.
