Spin-dependent hybridization and magnetic order of Ce/Fe(1 1 0) studied by spin-resolved resonant photoemission

Electronic and magnetic structures of the Ce/Fe(1 1 0) system were studied by means of spin- and angle-resolved resonant photoemission. Antiferromagnetic coupling of Fe 3d and Ce 4f spin magnetic moments was concluded from spin-resolved photoemission measurements supported by the electronic structure calculations. The relative intensity of the minority-spin component of hybridization feature at the Fermi level is larger than the majority-spin one, that can be assigned to spin-dependent hybridization between 4f and valence-band electrons induced by Fe substrate.
