Abstract

The NdFeB films have both crystal and amorphous structures dependent of film composition. The direction of the easy magnetization is normal to the film plane. The saturation magnetization and the coercivity were about 1000 emu/cc and 1.5 kOe, respectively. This film may be very useful for using the perpendicular magnetic recording media.
