Magnetization and magnetic anisotropy of Fe/Co multilayers: A first-principles calculation


The magnetic properties of bcc Fe/Co (001) multilayers are calculated from first-principles by means of the full potential linear muffin tin orbital method (FLMTO). 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 Co bulk are also verified. The results for the magnetization and MAE agree well with experimental results.
