Abstract [en]

An x-ray magnetic circular dichroism study of a polycrystalline Co/CoO   bilayer is presented. Using both the chemical specificity and surface   sensitivity in the core level techniques, we find that uncompensated   Co2+ spin moments participate in the remanent ferromagnetic response of   the bilayer that has oxygen nearest neighbors. These are likely located   at the Co/CoO interface. As intermixing of magnetic species is not   present in Co/CoO, it is concluded that the observed interface moments   are due to interface roughness. Given their direction, these moments   appear to not directly correlate to the exchange bias in these bilayers.
