Abstract
We report X-ray Magnetic Circular Dichroism (XMCD) measurements performed at the L_{II, III} edges of Ir in Cr_0.975Ir_0.025O₂. The data were recorded in transmission mode at beamline 6 of the European Synchrotron Radiation Facility. They allow us to determine the z projection of the orbital angular momentum of the hd electrons of Ir. The results obtained by the XMCD technique at the Ir edges and ¹⁹³Ir Mössbauer spectroscopy are compared.
