| 9 | THERMAL STABILITY AND PERPENDICULAR ANISOTROPY OF AMORPHOUS TbFeCo FILMS显示文摘The perpendicular anisotopy,coercivity and Kerr rotation angle of the amorphousTb32Fe54Co14 films were studied.The X-ray,electron diffraction,XPS and AES profile con-firmed that no obvious change in their amorphous structure and oxygen concentration is ob-served after annealing at 100℃,while their properties alter evidently under bending stress.Itseems to be believed that the perpendicular anisotropy in the Tb32Fe54Co14 films mainly arisesfrom the induced stress during preparation and the magnetostriction coupling stress,as wellas,the thermal instability of the film relates closely to the stress relaxation during annealing. | Lü Jian WANG Yinjun MA Ruzhang LU Jian | 1990 | Acta Metallurgica Sinica(English Letters)1990，3，9： | 0 |
