The ${\rm AB}_{p} {\rm C}_{1{-} p} $ type of mixed‐spin ferro–ferrimagnetic ternary‐alloy with the spins S A = 1, S B = 3/2, and S C = 1/2 is investigated on the Bethe lattice on which the A ions are distributed only on the odd shells and B or C ions are distributed randomly on the even shells with the probabilities p and 1 − p , respectively. The phase diagrams are studied for given probabilities p , the ratio of bilinear interaction parameters $R = |J_{{\rm AB}} |/J_{{\rm AC}} $ and the coordination numbers z = 3, 4, 5, and 6 with respect to the reduced temperature. It was found that the critical lines are seen at higher temperatures for higher q , otherwise they are qualitatively similar, therefore, the phase diagrams are only given for q = 6. In addition to the critical temperatures, the model also displays up to four compensation points for appropriate system parameters.
