    On the interface magnetism of thin oxidized co films: orbital and spin moments
    (Institute of Physics, 2009-03-25) Mulders, AM; Loosvelt, H; Rodriguez, AF; Popova, E; Konishi, T; Temst, K; Karis, O; Arvanitis, D; van Haesendonck, C
    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. © 2009, Institute of Physics
