Abstract

We present a fast and reliable method for investigating the magnetic properties of nanostructures. It combines the standard Monte Carlo and scaling techniques to allow results for such systems to be obtained by carrying out calculations for much smaller systems. The method is illustrated by applying it to the well-known problem of determining the single-domain limit of a cubic magnetic particle with an easy axis parallel to one of the cube directions. Results are in good agreement with those of micromagnetic calculations. © 2006 The American Physical Society.
