PARTICLE INTERACTION IN NUMERICAL MICROMAGNETIC MODELING

Numerical micromagnetic modeling of a single particle and small numbers of particles has recently greatly increased our understanding of fine particle magnetizing processes, but the behavior of a large number of such interacting particles is not yet completely understood. The analysis presented here shows that the moving-model Preisach approach, as a framework for explaining the behavior of such a distribution, is plausible; however, the proportionality factor is considerably different from the one that had been previously calculated.
