Abstract

We have for the first time observed K-edge X-ray magnetic circular dichroism of submonolayer amounts of adsorbates on ferromagnetic thin metal films. The O K-edge X-ray magnetic circular dichroism (XMCD) of CO adsorbed on fccCo grown epitaxially on Cu(001) showed a positive sign for the O1s ?2 ?*transition, which implies an opposite orbital moment of O to the Co magnetization.
