Abstract

We have studied perpendicular anisotropy in ultrathin Au/Co/Au(1 1 1) films. Misfit strain in Co grown on the Au-underlayer increases monotonically with increasing Au thicknesses from 0 to 5 monolayer (ML). We find that the interface anisotropy shows an abrupt increase for 2 ML of Au-underlayer. The volume anisotropy is larger than the magneto-crystalline anisotropy.
