摘要
An original approach is proposed to study the dipole-dipole interparticle interactions in dispersed magnets. It is the registration and analysis of the noiselike ferromagnetic resonance fine structure, which is caused by the magnetic dipole-dipole interaction between magnetic domains. The features of fine structure formation are discussed. The experimental examples of the possible applications of the fine structure method are given.
