Computational simulations are widely used across the engineering and science disciplines to complete experimental and theoretical studies. In the research and development of magnetic devices, computational micromagnetic simulations are a powerful tool that allows not only to predict the macroscopic magnetic properties of a sample, but also to understand the microscopic distribution of magnetic moments (the magnetic texture) that is otherwise difficult to explore with experimental tests. The present work makes use of the micromagnetic simulation program OOMMF (Object Oriented MicroMagnetic Framework), which is an open source domain program written in C++. The input for the program is a text file that is used to define the sample geometry and all the simulation conditions (model).
