“…Normally, simulated properties focuse on magnetic properties and consider the influence of exchange parameters, Zeeman effect, and the magneto-crystalline anisotropy [14,15]; however, these simulations do not consider changes in position due to external causes, such as an external pressure applied to a material. The influence of an external pressure on the final magnetic properties of a magnetic material is of great importance in applications for elastomers and allows one to adapt a built device to several geometries and uses.…”

In this work, Monte Carlo simulations of magnetic properties of thin films, including the influence of an external pressure, are presented. These simulations were developed using a Hamiltonian composed by terms that represent the exchange interaction, dipolar interaction, Zeeman effect, monocrystalline anisotropy, and pressure influence. The term that represents the pressure influence on the magnetic properties was included, since for many applications, magnetic materials are a part of a multiferroic material together with a piezoelectric or a ferroelectric compound. Initially, the model was developed using generic parameters, in order to probe its suitable performance; after that, parameters were adjusted for simulating thin films of La0.67Sr0.33MnO3, a manganite with several technological applications because its Curie temperature is greater than room temperature. Including the pressure influence, it was observed the formation of several kind of FM/AF configurations as strip, labyrinth, and chess board forms. Furthermore, it was observed that, as the pressure increased, the critical temperature tended to decrease, and this result was in agreement with experimental reports.
