摘要：
The exchange-coupling interaction between magnetically soft and hard grains in nanocomposite Nd2Fe14B/alpha-Fe and their effects on the effective anisotropy of materials have been investigated. By testing six different functions, series of curves of effective anisotropy constant versus grain size and volume fraction of the soft phase were obtained. The calculated results show that the effective anisotropy constant decreases with the reduction of grain size and increases with the decrease of the volume fraction of the soft phase. The calculated curves resemble the experimental results.
