Effects of the elemental layer thickness on the properties of Fe/Co grown at 200 °C

► Fe/Co multilayers were e-beam evaporated onto glass and Si substrates at 200 °C. ► The elemental layer thickness was changed. On glass, large in-plane anisotropy ► Onto Si, perpendicular anisotropy because of a large intermixing ► The perpendicular anisotropy is due to the absence of a pure Co layer. ► The type of in-plane anisotropy is controlled by the Fe/Co thickness ratio.
