Abstract
We have developed an in situ spin-wave Brillouin light scattering system, for the study of surface magnetic anisotropies under an ultrahigh vacuum. The surface uniaxial anisotropy constant is determined as -1.1mJ/m2 for a bare surface of Co(0001), indicating a strong in-plane anisotropy. With only 0.5 monolayer (ML) of Cu deposited on, the strong perpendicular anisotropy is induced, which is followed by an intensity peak at 1 ML of the Cu. We attribute these results to a steep change in the surface electronic state due to the Cu-atom deposition.
