Abstract
Based on the Monte Carlo calculation, we have investigated the magnetic behavior and the magnetocaloric effect of the nanoporous graphenes of a mixed spin ferrimagnetic (2, 3/2). We start by discussing the ground state phase diagrams corresponding to several physical parameters at the temperature T=0 K. In addition, the reduced critical and compensation temperatures have been found with distinct values of the number of lattice sites (L). The influence of the parameter L, reduced exchange couplings Rσσ, Rsσ, and the reduced crystal field on the total magnetic and hysteresis cycles has also been studied. We begin by exploring the impact of the reduced external magnetic field on the specific heat (Cp), magnetic entropy change (-∆Sm), adiabatic temperature change (ΔTa), and relative cooling power (RCP). These results indicate that the nanoporous graphene compound could be a promising candidate for magnetic refrigeration technology.
