Influence of a new long-range interaction on the magnetic properties of a 2D Ising layered model by using Monte Carlo method

Abstract

This paper presents a novel interpretation of the long-range interaction in interlayers to analyze the magnetic properties of a 2D Ising layered model. To describe the long-range interaction, spin chains are introduced, while magnetic and thermodynamic behaviors of the 2D Ising layered model are investigated by Monte Carlo methods. Phase diagrams in various parameter planes are produced. Furthermore, we investigate the hysteresis behaviors and critical exponents, which are consistent with previous findings. Finally, we analyze the magnetocaloric effects, including entropy change and relative cooling power (RCP), caused by different Hamiltonian parameters.
