The present invention provides an apparatus comprising a rare earth permanent magnet powder, a bonded magnet and the bonded magnet. The rare earth permanent magnet powder is composed mainly of Fe N, of 0.1-1.5at% of Si and the balance 7-12at% of Sm, the 0.1-1.5at% M, 10-15at%, of which M is Be, Cr , and Al, Ti, Ga, Nb, Zr, Ta, Mo, at least one element of V, the main phase of the rare earth permanent magnet powder is a TbCu 7 structure. By adding the Si element in the rare earth permanent magnet powder enhances the ability to form an amorphous structure of SmFe alloy, and by improving the wettability of the alloy liquid with the addition of a constant amount of the element M allows the alloy liquid is ejected from the melting device and to make it easier. The average particle size of the rare earth permanent magnet powder is 10-100μm and also the rare earth permanent magnet powder is composed of the nanocrystalline or amorphous organization average grain size is 10-120nm.
