Abstract

The phase diagram of the AB~p~C ~1–p~ ternary alloy consisting of different Ising spins S^A^ = 3/2, S^B^ = 2, and S^C^ = 5/2 in the presence of a single‐ion anisotropy is investigated by the use of a mean‐field theory. At finite temperature by changing values of the parameters of the model different types of phase diagrams are obtained, including critical end points and isolated critical points.
