Abstract

Based on Monte Carlo simulation, a mixed-spin (5/2, 2, 3/2) Ising model is constructed to investigate the dynamic magnetic properties of antiferromagnetic/ferromagnetic YMnO3/FM bilayer under a time-dependent magnetic field. The effects of exchange interaction, magnetic field and temperature are involved in this work. Masses of numerical results of the dynamic order parameter, susceptibility, internal energy, and critical temperature are obtained under the influence of the diverse physical parameters. Moreover, the phase diagrams and the hysteresis loops of the system are discussed.

Highlights

Multifunctional ceramics material, a kind of functional materials with rich application, has received extensive attention and numerous research results in the past decades [1,2]
YMnO3 is a one-multiferroic compound with perovskite crystal structure and it can exhibit antiferromagnetism and ferroelectricity in magnetic field and electric field, respectively, at room temperature[6,7,8]
When the ferromagnetic and ferroelectric materials were applied to a time-dependent magnetic or electric field, it is practical and interesting to investigate the dynamic properties of these systems theoretically

Summary

Introduction

Multifunctional ceramics material, a kind of functional materials with rich application, has received extensive attention and numerous research results in the past decades [1,2]. When the ferromagnetic and ferroelectric materials were applied to a time-dependent magnetic or electric field, it is practical and interesting to investigate the dynamic properties of these systems theoretically. Much effort was made on the magnetic and dielectric properties of the low-dimensional mixed-spin nano-systems using Monte Carlo simulations [33,34,35,36,37,38] Such BiFeO3/FM bilayer system was investigated [39,40,41]. In this work we investigate the dynamic properties of a mixed-spin (5/2, 2, 3/2) YMnO3/FM bilayer system under the existence of a time-dependent oscillating magnetic field.
