Dynamic phase transitions on the kagome Ising ferromagnet

Abstract

We perform extensive Monte Carlo simulations to investigate the dynamic phase transition properties of the two-dimensional kinetic Ising model on the kagome lattice in the presence of squarewave oscillating magnetic field. Through detailed finite-size scaling analysis, we study universality aspects of the non-equilibrium phase transition. Obtained critical exponents indicate that the two-dimensional kagome-lattice kinetic Ising model belongs to the same universality class with the corresponding Ising model in equilibrium. Moreover, dynamic critical exponent of the local moves used in simulations is determined with high precision. Our numerical results are compatible with the previous ones on kinetic Ising models.

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

“…Based on the MC simulations, Z. D. Vatansever studied the effect of system sizes on dynamic phase transition behaviors of the Kagome lattice in the presence of a square-wave oscillating magnetic field. The results indicate that the phase transition temperature increases with the increase in system size [45]. In this study, based on a fixed system size, we used MC simulations to demonstrate the dynamic magnetic properties and magnetocaloric effect of a single-layer Kagome lattice under dynamic magnetic fields.…”
