Spin-glasses in amorphous (Ni_(100-x)Fe_x)₇₉P₁₃B₈ alloys

Creators

Abstract

Dilute amorphous (Ni_(100-x)Fe_x)₇₉P₁₃B₈ alloys exhibit usual characteristics of spin glasses : freezing temperatures T_M (sharp cusp in zero-field susceptibility) proportional to x up to x=4 at. %. However, the magnetization does not follow the Blandin-Souletie-Tournier scaling laws. Such an anomaly can be explained within a model of ferromagnetic clusters coupled bt RKKY interaction.
