Abstract

Amorphous Co_93-xTb_XZr₇ thin films with a well-defined in-plane uniaxial anisotropy were prepared by RF sputtering. The saturation magnetization 4πM_s, the uniaxial anisotropy constant K_u and the coercive field H_c were studied as a function of temperature and for the composition range 0 < X < 7. The Tb moment at 4.2 K is found to be 9μ_B in agreement with the theoretical value. This would indicate a collinear spin structure for Tb. The mean-field theory has been used to explain the temperature dependence of the magnetization. The exchange interactions between Co-Co and Co-Tb atom pairs have been evaluated. K_u and H_c are related by the equation H_c = αK_un/μ0M_s with the fitting parameters α and n.
