Dependence of Effective Anisotropy on Grain Size in Nanocrystalline Nd2Fe14 B Hard Magnetic Material

Taking nanocrystalline Nd2Fe14B as a typical sample, based on Herzer's random anisotropy theory and the cubic grain model, the partial exchange-coupling interaction model was established and the dependence of effective anisotropy constant Keff on grain size was investigated. Calculation results...
