Insight into the magnetic properties and magnetocaloric effect of a MBene-like monolayer

Abstract

MBene, as a subset of the innovative two-dimensional material MXene, has attracted considerable research attention in recent years. The present study uses Monte Carlo simulation to investigate the magnetic behaviors, thermodynamic characteristics, and magnetocaloric effect of MnB. Our results indicate that reducing the exchange couplings and absolute magnitudes of the crystal field, or conversely, increasing the external magnetic field, can enhance the maximum values of the isothermal magnetic entropy change. In addition, the effects of the crystal field, exchange couplings and external magnetic field on the relative cooling power are investigated.
