摘要：

The influence of internal stress on the magnetic anisotropy and the magnetostriction was investigated in sputter-deposited amorphous (Tb0.27DY0.73)(0.42)Fe-0.58 films. Films with tensile stress show in-plane anisotropy and giant magnetostriction of lambda(parallel to)=400X10(-6) at 1 T measured in a field parallel to the film plane at room temperature. The magnetostriction rises rapidly to lambda(parallel to)=200X10(-6) at 0.05 T and the coercivity is less than 0.01 T. On the other hand films with compressive stress show perpendicular anisotropy and still higher magnetostriction of lambda(parallel to)=540x10(-6) at 1 T; however, this is by far a slower increase of magnetostriction at small fields. This different behavior is explained by considering the nature of magnetization processes, i.e., domain-wall motion and spin rotation.
