According to the ferrous magnetic structure arrangement of atomic matrix in the rare earth - transition metal thin film, the magnetic dipole model of TbCo non-crystalline film of perpendicular magnetic anisotropy in has been established, with which Ku of the perpendicular magnetic anisotropy in TbCo non-crystalline film＇s change with the temperature to be calculated. Compared with the experimental result, we find that the mutual effect of dipole magnetism between atoms of the rare earth, the transition metal and the rare earth - transition metal is only the ...
