Description
Summary:A thorough understanding of the magnetocaloric properties of existing magnetic refrigeration materials has always been an essential point in magnetic refrigeration technology. This work aims to study the magnetic properties and magnetocaloric effect (MCE) of (7/2; 3/2) ferromagnetic 2D Ising model. We analyze the next coupling interaction and external magnetic field effect on some magnetic and magnetocaloric properties of S = 7 / 2 and σ = 3 / 2 mixed-spin square lattice such as the isothermal entropy change, the adiabatic temperature change, and the relative cooling power (RCP). The obtained results show that the system has interesting magnetocaloric properties associated with the ferrimagnetic order near the compensation temperature T comp ; especially, the isothermal entropy change reaches its maximum near T comp .
