Magnetization and magnetic anisotropy of Fe/Co multilayers: A first-principles calculation
Abstract
The magnetic properties of bcc Fe/Co (001) multilayers are calculated from first-priciples by means of the full potential linear muffin tin orbital method (FPLMTO). A significant enhancement in the magnetic moments of each atom in the multilayer is observed. The magnetization and magnetic anisotropy energy MAE are described as a function of Fe/Co layer thickness ratio. For comparison with the obtained multilayer values, the magnetization and MAE of constituent atoms, bcc Fe and a theoretical bcc Co in bulk are also verified. The results for the magnetization and MAE agree well with experimental results.
