Although the structure of Fe_ (16) N_2 has been known for a long time, "the great interest in its research began with the discovery of its singularly high saturation [r r r r r r r r r n Magnetization (Bs-258 T Yan after the preparation of a high content of Bi Chuan. Research in both bulk and thin film materials are very active l ’4]. R r r r r r r r However, since it is a metastable phase, so far only Japan’s Sllgita ’group has prepared Fe_ (16) N_2 single crystal on a semiconductor substrate Film and verified that its saturation magnetization at room temperature is much higher than that of the Slaterwaaling curve by 29. About the knife has such a high saturation magnetization The value has become a hot topic of debate in the field of magnetism theory. The author has done a detailed study of the sputtering conditions of each phase formed of iron nitride Affect the boring, in this paper prepared by sputtering a’’xe into the single crystal film, well-clear to observe the [l and [110] direction Of the electron diffraction pattern.Magnetic measurements show that the saturation magnetization value of high r r r r r r r n up to 264 ~ 289 Wbha ’.
