Abstract

In this work the magnetic anisotropies of magnetostriction material Tb(Fe_0.55Co_0.45)1.5 (named a-TerfecoHan) films were investigated with respect to working pressures in the range 1-7 mTorr. The results obtained show that perpendicular magnetic anisotropy (PMA) can be obtained at a working pressure above 5.1 mTorr. XRD was utilized to clarify the origin of the PMA observed in Tb(Fe_0.55Co_0.45)_1.5 films, and revealed that all samples were amorphous. Therefore, we propose that the PMA effect is explained by stress produced in film due to internal relaxation process and magnetic anisotropy enhancements caused by magnetoelastic interactions.
