Hard and Soft X-MCD Studies of CrO2

Abstract
Chromium dioxide is investigated by X-MCD measurements on the Cr L2,3 , Cr K-edges and on the
O K-edge in combination with Ligand Field Multiplet Model (LFM) calculations and Linearized Augmented Plane
Wave (LAPW) band-structure calculations. Applying so called Sum Rules [2, 3] to the Cr L2,3- edges one deduces
an upper limit for the orbital-moment of 10-2µB which is in good agreement with magneto-meter-measurements.
Both Cr K-edge and O K-edge X-MCD measurements reflect a significant polarization of the p-like bands and are
well described by a spin-density calculation.
