Cover Story: Co-based amorphous metal nanocomposites (MANCs) are a material of interest for future use in power electronics applications. Faulting and Mn partitioning behavior has been observed in these materials. To understand these behaviors, we performed first principle calculations to gain insights into the faulting and magnetic behaviors of these types of materials. We found that the faulting and magnetic behaviors are both susceptible to variation depending on the partitioning and percentage of Mn within a volume of Co, such that we can tailor these behaviors as necessary via controlling the Mn doping within these MANCs.
