  We use x-ray absorption and magnetic circular dichroism to study electronic
configuration and local susceptibility of CePt5/Pt(111) surface alloys from
well above to well below the impurity Kondo temperature. The anisotropic
paramagnetic response is governed by the hexagonal crystal field and
ferromagnetic correlations, with modified parameters for Ce moments residing
next to the alloy surface. Quantitative XMCD evaluations provide direct
evidence of Kondo screening of both spin and orbital 4f moments. Magnetic
signatures of coherence are not apparent for T >= 13 K.
