Abstract

This study employs molecular-dynamics simulations to predict the distribution function of diluted magnetic Co atoms in a Cu host and then uses the Weise mean-field theory and the Ruderman-Kittel-Kasuya-Yosida theory to calculate the magnetic properties of the Co-Cu alloys. Specifically, this study investigates the dependency of the nanoparticle magnetization on the Curie temperature for Co-Cu alloys with five different Co concentrations. The proposed method successfully overcomes the limitations of molecular-dynamics simulation in magnetic studies, for diluted systems at least.
