Abstract

Co/Ag/Ge (111) films show an in-plane anisotropy as deposited at 200K. The ferromagnetic inactive layers, formed due to the intermixing of Co and Ge, can be efficiently reduced to zero thickness by introducing 6 monolayer (ML) Ag as a buffer layer. For Co/3ML Ag/Ge (111) films, the amount of Ag is not enough to separate Co and the Ge substrate. This results in the formation of a 2-monolayer-thick nonferromagnetic Co-Ge compound layer and a rough interface of the Co layer.
