This work introduces a combination of three factors for explaining the possible causes of “magnetic domains” presented in experimental reports. The first factor is the combination of a ferromagnetic (FM) interaction between first neighbors with a

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

Grain boundaries in polycrystalline thin films with crystallite sizes at nanoscale presents regions characterized by a high degree of local structural disorder. As a consequence, great values of the associated local anisotropies are expected. On this

In this work, a complete model for studying the magnetic behaviour of polycrystalline thin films at nanoscale was processed. This model includes terms as exchange interaction, dipolar interaction and various types of anisotropies. For the first term,

In this study, a methodology, for polycrystalline magnetic thin films construction composed by nano-grains, was developed. The size and shape of grains and samples under scale considerations of magnetic materials were developed, taking into account p

An atomistic scale study of ultra-thin ferromagnetic films was carried out using Monte Carlo simulations with Metropolis dynamics, and the simulations were performed using a Heisenberg Hamiltonian, surface and crystalline anisotropies, and dipolar in

A study of the magnetic behaviour of polycrystalline thin films as a function of their thickness is presented in this work. The grain volume was kept approximately constant in the virtual samples. The model includes the exchange interaction, magneto-

In this work we present a new design of Co based bit pattern media with out-of-plane uni-axial anisotropy induced by interface effects. Our model features the inclusion of magnetic impurities in the non-magnetic matrix. After the material model was r
