Dynamic magnetic behaviors and magnetocaloric effect of the Kagome lattice: Monte Carlo simulations

Abstract

Based on the Monte Carlo method, we examined the dynamic magnetic behaviors and magnetocaloric effect of a Kagome lattice subjected to the influence of time-dependent oscillating and time-independent magnetic fields. We used the Ising model to describe the Kagome lattice and study the dynamic order parameters, blocking temperature, internal energy, and phase diagrams. The results revealed that exchange coupling increases the stability of the system and the bias field induces order; however, the time-dependent oscillating magnetic field induces disorder. In addition, the magnetocaloric properties, changes in magnetic entropy, and relative cooling power of the Kagome lattice were investigated.

“…Based on the results of our previous studies, we successfully applied EFT and MC to investigate the magnetic properties of 2D materials, such as borophene and graphene [15][16][17][18][19][20][21][22][23][24][25][26]. The results revealed the distinct magnetic properties exhibited by the 2D materials, demonstrating their novelty compared to their bulk counterparts.…”
