Abstract
We have for the first rime observed K-edge X-ray magnetic circular dichrois m of submonolayer amounts of adsorbates on ferromagnetic thin metal films. The O K-edge X-ray magnetic circular dichroism (XMCD) of CO adsorbed on fcc Co grown epitaxially on Cu(001) showed a positive sign for the O1s --> 2 p i* transition, which implies an opposite orbital moment of O to the Co magn etization.
