摘要
As a complement to the experimental analysis of magnetization reversal in a two-phase system, a numerical micromagnetic three-dimensional calculation is developed and tested. It is applied to a set of 64 nanometer-scale hard (Nd2Fe14B) and soft (Fe3B) cubic grains. Calculations reproduce qualitatively the experimentally observed processes and allow the relation between the structure and the coercivity mechanism in nanocomposite hard magnetic materials to be better understood.
