A route towards finding large magnetic anisotropy in nano-composites: application to a W1-xRex/Fe multilayer
Abstract
We suggest here a novel nano-laminate, 5[Fe]/2[WxRe1-x] (x=0.6-0.8), with enhanced magnetic hardness in combination with a large saturation moment. The calculated magnetic anisotropy of this material reaches values of 5.3-7.0 MJ/m3, depending on alloying conditions. We also propose a recipe in how to identify other novel magnetic materials, such as nano-laminates and multilayers, with large magnetic anisotropy in combination with a high saturation moment.
