Abstract
MBene is a branch of the new two-dimensional (2D) material MXene. Due to its high stability, good electrical conductivity, and excellent electrocatalytic performance, MBene shows great potential in energy storage and electrocatalysis. In this work, we used Monte Carlo simulation to study an MBene-like material described by a mixed-spin (5/2, 2) Ising model. We discuss the effects on the dynamic magnetic characteristics of the system, including dynamic order parameters and hysteresis loops, caused by the crystal field and exchange coupling. We found that the system can exhibit the behavior of double compensation temperatures. Increasing the absolute values of the exchange coupling or decreasing the absolute values of the crystal field can increase the coercivity and the area of the dynamic hysteresis loop.

Physica A: Statistical Mechanics and its Applications
Recognized by the European Physical Society
Physica A publishes research in the field of statistical mechanics and its applications.
Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents.
Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
