Abstract
The coercive field of explosion sintered Sm2Fe17Nx magnet is analysed on the basis of micromagnetism. Results indicate that the coercivity o f explosion sintered Sm2Fe17Nx magnet is controlled by the nucleation field near the grain surface. The large demagnetization factor origina tes from the strong strayfields of nonmagnetic poles, magnetically sof t phases, and the very sharp corners of Sm2Fe17Nx grains.
