Here, we have investigated the magnetic properties and magnetocaloric effect of the alternate layers of nanoborophene like of a ferrimagnetic mixed spin 2 and 3/2 in a Blume–Capel model, employing the Monte Carlo method. The ground states at different parameters planes are found. Besides, we also determined the reduced compensation temperature and critical temperature to vary the number of layers (L). The impact of L, reduced exchange couplings Rσσ, RSσ, and reduced crystal field on the total magnetizations. In addition, the various parameters L, Rσσ, RSσ, and t also have distinct influences on the hysteresis loop are also analyzed. The Cp, -ΔSm, and ΔTa as a function of reduced temperature under the effect of several reduced external magnetic fields were discussed. Lastly, the impacts of the reduced external magnetic field on the relative cooling power were also studied. We hope that these results can be used as a basis for the application of materials, spintronics, energy storage, and magnetic refrigeration devices.
