摘要
To explain the ferromagnetic resonance (FMR) for fine particle systems with parallel easy axis, a model based on the Preisach model is proposed. This model allows us to express the interaction field between particles and the anisotropy field, necessary in calculation of individual FMR susceptibility of the particles of the system. The system susceptibility is computed from the individual particle susceptibilities. Even if the model is phenomenological, it is able to explain the FMR particle system behavior and predict experimental facts.
