In-plane susceptibility of amorphous ferrimagnetic films near the compensation point

Abstract

The in-plane susceptibility χp of several amorphous sputtered GdCoMo films shows a minimum of ∼3×10-4 emu at the compensation temperature. This value is accounted for theoretically by the classical antiferromagnetic susceptibility relation. The contribution to the in-plane susceptibility of composition inhomogeneities is also calculated. The fact that such an increase in susceptibility is not observed in experiment indicates the films are quite homogeneous magnetically. Comparison of the anisotropy in films prepared at high and low deposition rates indicates the effect of rate on anisotropy is weak.
