Simulating the magnetic susceptibility of magnetic nanowire arrays

Abstract

We study the magnetostatic interaction and relaxation of nanomagnetic wires in arrays using a Monte-Carlo model. Using this model we describe the magnetic behavior of a two-dimensional array of high aspect ratio ferromagnetic, single-domain nanowires, ordered parallel to one another in a nonmagnetic template. We use this model to determine stable configurations and hysteresis loops, and also investigate the mean field behavior of a typical nanowire array to determine the influence of the geometrical and magnetic parameters on the behavior of the array.
