Abstract: The demangetization curves for the nanocrystalline Nd-Fe-B magnets of the stoichiometric com position were calculated by using the finite element technique of micromagnetism, The curve, especially iHc become smaller with increase of N. The most small iHc from a series of the curves along different field directions is closer to that for N＝∞. iHc increases with increase of L. and are close or some what smaller than that the experimental values should be.
