Observation of O K-Edge X-Ray Magnetic Circular Dichroism of CO Adsorbed on an Ultrathin Co/Cu(001) Film

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 fcc Co grown epitaxially on Cu(001) showed a positive sign for the O1s →2 π...

Description
Summary:	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 fcc Co grown epitaxially on Cu(001) showed a positive sign for the O1s →2 π * transition, which implies an opposite orbital moment of O to the Co magnetization.
