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.
