Members of the Nanomagnetism Group measured X-ray Spectroscopy in the soft X-rays (100 to 1500 eV) energy range in the Planar Grating Monochromator (PGM)-beamline in Campinas Brazil. Mr. Alexander Cardona (Phd student), studied during his visit the magnetism of BiFeO3 NPs looking at the L2,3-edge of Fe and k-edge of O.
