Demagnetization curves for nanocrystalline Nd 2 Fe 14 B magnets were calculated by using the micromagnetic finiteelement technique. The shape of the grains is either cubic or tetrakaidecahedral. If the grain number N of the magnet is small, the calculated curve, especially that for m 0i H c , strong
