Abstract

Spin- and angle-resolved resonant (Ce 4d→4f) photoemission spectra of a monolayer Ce on Fe(110) reveal spin-dependent changes of the Fermi-level peak intensities. That indicate a spin-dependence of 4f hybridization and, thus, of 4f occupancy and local moment. The phenomenon is described in the framework of the periodic Anderson model by 4f electron hopping into the exchange split Fe 3d derived bands that form a spin-gap at the Fermi energy around the Γ point of the surface Brillouin zone.
