Abstract

The paper analyzes the temperature influence on the magnetic behavior of a 2D square network of ferromagnetic Ni nanowires. Numerical micromagnetic simulations were performed in order to better understand the magnetic behavior of magnetic nanowire systems, the magnetic interaction between wires and the role of the temperature in defining the magnetic state of individual wires and of the wire system. The nanowire system was studied using an Ising type model; the hysteresis loops and the temperature dependence of the coercive field and magnetic remanence were obtained. In order to increase model's accuracy micromagnetic simulations were carried out in order to improve upon the expression for the energy barrier in the Monte-Carlo-Metropolis.
