The mixed-spin ternary-alloy consisting of half-integer spins

► Mixed-spin ferro-ferrimagnetic ternary-alloy on the Bethe lattice was investigated. ► The odd shells contain only A (spin-12) atoms. ► The even shells either contain B (spin-32) or C (spin-52) atoms randomly. ► The critical temperatures, i.e. the phase diagrams, were obtained. ► Only one compensation temperature was found.
