Concentration influence on magnetocaloric effect of ferromagnetic ternary alloys

Based on the Monte Carlo simulation, magnetic properties and magnetocaloric effects of a two-dimensional body-centered hexagonal structure with mixed spin (1/2, 1, 3/2) ferromagnetic ternary alloys of the type A(y)(B1-xCx)(1-y) were studied. To this end, concentration, temperature and an external magnetic field effects on the magnetization and magnetocaloric effect of these structures were examined. Our results indicate that concentration and external magnetic field play a crucial role in magnetic properties and magnetocaloric effect of these ternary alloys. Also, it is observed that A(0.2)(B0.4C0.6)(0.8) compound has the largest cooling efficiency and thus is a suitable material for magnetic refrigerator.
