Abstract

Ce unoccupied 5d electronic states of the nonmagnetic heavy-fermion compound CeRu2Si2 have been investigated by means of x-ray magnetic circular dichroism (XMCD) experiments. We measure the magnetic field dependences of the Ce L2,3-edge XMCD of a powder sample with a transmission mode at about 2 K. The magnetic field dependence of the L2-edge x-ray absorption spectrum shows a slight enhancement of the white line with metamagnetic behaviour, indicating reduction of the c-f hybridization. The L2 XMCD spectrum shows a single positive lobe, while the L3 XMCD spectrum consists of a main negative peak and two small negative satellite peaks. The main structure of CeRu2Si2 is similar to that of CeRu2Ge2.
