Phase separation in binary alloys with one magnetic component

Abstract

Phase separation and magnetic ordering in segregating binary alloys with one magnetic component are studied within the mean-field approximation. The influence of magnetism on the phase-separation transition temperature ($T_{\mathrm{CS}}$) is examined in detail. In general it is found that magnetism increases $T_{\mathrm{CS}}$ and causes strong asymmetries in the phase diagram. Results for the phase diagrams and for the temperature dependence of the magnetic and spatial order parameters for various cases are presented.
