Analyzing the magnetic interactions in nanostructures that are candidates for applications in spintronics

Abstract
Abstract It is very common for the qualitative study of magnetic interactions in nanostructures to lead to applications in spintronics. In this paper, a model is presented to calculate the magnetic interactions in nanostructures. The model can determine quantitative values for the types of magnetic states in the sample, which can be demagnetized or magnetized. Each magnetic interaction provides information on the magnetic behavior of the nanostructure and opens possibilities for spin-wave excitations. For the model application, numerical simulations were carried out on nanostructures of type nanowires and hexagonal nanowire arrays. Each nanowire is one chain of interacting ellipsoidal grains.
