Abstract

Magnetic properties of 0.4 monolayer Co grown epitaxially on Cu(001) were investigated by X-ray magnetic circular dichroism (XMCD) using our newly constructed ultrahigh vacuum system equipped with a 7 T superconducting magnet and a liquid He cryostat. The angle-dependent XMCD spectra for the saturated magnetization recorded at 6.0 K allowed us to evaluate separately the spin and orbital magnetic moments along the surface parallel and normal directions. Enhancements of the magnetic moments compared with the corresponding bulk values were clearly elucidated: ∼15% for the spin magnetic moment and ∼96 and ∼53% for the orbital magnetic moments along the surface parallel and normal directions, respectively.
