4. Crystal field effects in the L23XMCD of rare earth insulators

Abstract

We present the L23XMCD of insulating rare earth (oxides and fluorides). The paramagnetic samples were magnetised in a 7T field and cooled down to 5–10K. We compare our XMCD data with a recent model for a 4fN5d0electronic configuration. The L2edge displays a derivative shape, in agreement with the models. The L3edge however, is found to deviate, having a more complicated shape, due to the presence of quadrupolar contributions and, we argue, crystal field effects.
