摘要：

Anisotropy of the energy dependent polar magneto-optical Kerr effect as a function of the angle between the magnetization and crystallographic axes is reported. These results are obtained on epitaxially oriented optically opaque films of hcp Co grown in two different crystallographic orientations by molecular beam epitaxy. Respective Kerr spectra of fcc Co films are found to be insensitive to the magnetization direction. This Kerr anisotropy is correlated with the presence of strong magnetocrystalline anisotropy in the hcp phase of Co. A perturbation theory treatment of the spin orbit coupling correctly predicts the order of magnitude of this new effect.
