Monte Carlo simulations of dynamic phase transitions in ferromagnetic thin-films

Abstract

By means of detailed Monte Carlo (MC) simulations, we have presented dynamic phase transition (DPT) properties of ferromagnetic thin-films. Thermal variations of surface, bulk and total dynamical order parameters (DOP) for a film and total order parameter for the films with different thicknesses have been examined. Opposite regimes of the critical value of reduced exchange interaction (surface to bulk ratio) Rc at which the critical temperature becomes independent of film thickness L has been also taken into consideration. The average magnetizations of each layer is reversed in these regimes. Based on the results, we have confirmed that the system represents a crossover behavior in between ordinary to extraordinary transition in the presence of surface exchange enhancement.

Compensation temperature and hysteresis behaviors of a graphene-like bilayer: Monte Carlo Study

“…For example, the phase diagrams of the graphene monolayer were discussed [13]. Aktas et al researched the influence of thickness on magnetic behaviors in graphene-like layers [14]. R. Masrour et al revealed the significant role of defects on magnetization in the nano-graphene bilayer by using the Monte Carlo method [15].…”

Dynamic phase transitions on the kagome Ising ferromagnet

“…Several analogies between thermodynamic and dynamic phase transitions, for instance, similar phase diagrams, have been shown in theoretical and experimental studies [6,[17][18][19]. In addition, DPTs have been studied in a diversity of models such as nanoscale systems [20][21][22], systems with surfaces [16,[23][24][25][26].…”
