Considering different contact situations of grains, we effective anisotropies of magnetically soft α-Fe grains, investigate the effects of exchange-coupling interaction on hard Nd2Fe14B grains and NdaFe14B/α-Fe nanocomposite. An expression of effective anisotropy suitable for different degrees of ex...
