NdFeB permanent magnet has high remanence, maximum magnetic energy product and high coercivity, which has the highest performance price ratio in the third generation the rare earth permanent magnet. NdFeB permanent magnet can be applied to many fields like as automobile, medical treatment, computer, machinery, military and so on with increasing expansion in applications.So far, less study is devoted to the basic micro structure on molecular and atomic level of NdFeB compared with productive technology, which is put more attraction due to the osculation with manufacture and application. This trend would effect the rapid development of NdFeB to some degrees in a long time. The study of the interaction and the structure on the atomic level could deeply proclaim physicochemical properties, and offer fundamental theoretical direction for the production and application of the material.
