摘要

Monte Carlo study of the magnetic and magnetocaloric behavior of a mixed-spin (S = 3/2, σ = 2) Ising model on a Star-of-David monolayer lattice. The influence of the lattice size NL and the reduced crystal-field d on the total magnetization, magnetic susceptibility, and hysteresis behavior of the system is investigated. The effects of NL and the reduced external magnetic field h/Jsσ on specific heat and magnetic entropy changes are analyzed. The results show that a higher h/Jsσ leads to an increase in the maximum magnetic entropy change -ΔSmax. Additionally, a maximum of -ΔSmax = 0.0071 is obtained for a reduced magnetic field h/Jsσ = 1. Finally, the relative cooling power (RCP) is evaluated by increasing values of the h/Jsσ from 0.7 to 1 and reaching a value of about RCP = 0.0768.
