摘要：
Magnetization distribution in Nd-Fe-B nanocomposite magnets was investigated by electron holography, using a new pole piece apparatus dedicated to observations of nanocrystalline ferromagnetic materials. The exchange coupling between the magnetically soft and hard grains of 20-30 nm was experimentally verified by this microscopic study with improved resolution.
