Abstract
We describe the global mean-field phase diagram for a binary alloy that contains one magnetic component. We obtain 12 types of system phase diagrams, each of which displays a different interaction of chemical (segregration or ordering) and magnetic (ferromagnetic or antiferromagnetic) long-range order. Our results follow from the known features of the phase diagrams along the symmetric sections of Griffithss three-component (spin-1) model when both uniform and sublattice ordered states are considered. The multiple-phase coexistence and associated multicritical states of the spin-1 model appear in alloy language linked to previously unknown features such as first-order magnetic to paramagnetic transitions within chemically ordered phases, phase segregation among two magnetically ordered states, and first-order field-induced transitions.
