Abstract

The electron spin-resonance spectrum of Mg:Gd single-crystal alloys in the concentration range 50-1000 ppm exhibits a single anisotropic line. Both the field for resonance and the angular variation of linewidth can be described in terms of unresolved fine structure, but with substantially different values for the axial crystalline field constant. We propose a possible explanation for this difference. We discuss discrepancies between our conclusions and those of Salamon on a similar system.
