Abstract
The variation of X-ray magnetic circular dichroism (XMCD) with temperature has been measured at R L-2,L-3-edges in R3Fe5O12 (R=Gd and Er). A drastic c hange in the spectral profile has been observed at low temperatures. The va riation of XMCD peak intensity, corrected by the contribution of Fe with te mperature, is in agreement with the magnetization of R sublattice. The resu lts suggest that Fe 3d polarization plays an important role to produce the R L-2,L-3-edges XMCD spectrum.
