Fig. 30: XMCD spectra of various rare-earth insulators recorded at the L2-edge of the rare-earth absorbing element. The spectra of Gd3Ga5O12 TbF3 were measured in the paramagnetic phase with a high magnetic field (7 T) and at low temperature (<3 K). Note the great similarity of the spectra obtained for the paramagnetic sample Gd3Ga5O12 and the isostructural ferromagnetic compound Gd3Fe5O12.
