Abstract

The classical description of the electron spin resonance (ESR) phenomenon is based on the known Bloch equation (1946) for a motion of a vector magnetization in a variable magnetic field. In order to study the magnetic relaxation mechanism of ESR phenomena observed in a high intensity microwave field, the authors developed a statistical method of process simulation. Analysis of the calculations of magnetoresonance absorption evolution demonstrates that by taking into account the crystal fields and exchange interaction it is possible to apply this method in the research of more complicated magnetic structures such as ferromagnetics, asperomagnetics, spin-glasses, etc
