It was successed that Fe film with perpendicular magnetic anisotropy was prepared by the evaporation method from Fe_<100-x> Bi_x evaporant. The magnetic properties of deposited thin films is as follows; The saturation magnetization (4πMs) is larger than 20KG and the perpendicular anisotropy constant (K^+) is 4×10^5 erg/cc, on the thickness 0.3μm at Fe_<98.4> Bi_<1.6> evaporant. The film structure consists of regular column grains with excellent orientation in perpendicular direction to the substrate plane. One cause of the increase in the magnetization is thought to be the effect of a perpendicular configuration for Fe column grains which is constituted when Bi reevaporates. We investigated the process of the growth of the films by using X-ray diffractometer, AES analysis and SEM photographs.
