英文摘要：

The theories and models of the intergranular exchange-coupling interaction in the nanocrystaUine magnetic materials have been introduced. The effects of the exchange - coupling interaction on the effective anisotropy and magnetic properties in the single - phase nanocrystalline soft magnetic and hard magnetic materials were discussed briefly. The influences of the phase component, the grain size and microstructure of the nanocomposite permanent materials on the effective anisotropy and magnetic properties were investigated carefully.
