The mixed-spin ternary-alloy in the form of ABpC1−p on the Bethe lattice

►The ABpC1‐p type of mixed ferromagnetic‐ferrimagnetic ternary-alloy with A (spin-3/2), B (spin‐1) and C (spin‐5/2) ions was studied on the Bethe lattice with the odd numbered shells containing only A ions, while the even numbered shells either containing B or C ions randomly. ► The phase diagrams were obtained on the (R=|JAC|/JAB, kTc/JAB) and (p, kTc/JAB) planes forgiven values of p and R, respectively, with the coordination numbers z=3,4,5 and 6. ► The model presents one or two compensation temperatures for appropriate values of the system parameters. ► The qualitative difference, i.e. the concavity of the boundary lines in the previous Works appear to be convex in the current work, is also mentioned.
