Size, shape and temperature effects on Ferro/Antiferro-electric hysteresis loops from Monte Carlo simulations on 2D Ising model
Development and Application Systems（2014）
Abstract
A Monte Carlo (MC) simulation of a 2D microscopic Ising model is performed to study the relation between electric and thermal properties in a 2D lattice which exhibits Ferro-Electric (FE) and Anti-Ferro-Electric (AFE) coupling. The main purpose is to determine how the size and the shape of these crystals affect this relation at different temperatures. The different effects are discussed as a function of the relative strength of two parameters the Ferro and Anti-Ferro interaction constants for different applied cycling external electric field.
