Abstract
We present resonant soft x-ray Bragg diffraction data on the space-group forbidden (010) reflection at the Fe L-2,L-3 edges of magnetoelectric GaFeO3. Observed intensities give direct evidence for strange atomic multi-poles that violate both time and space inversion, in particular a magnetoelectric quadrupole. The discovery of magnetoelectric multipoles in the open 3d shell is a direct measure of coupling between magnetic and electric properties and a basis to a microscopic understanding of magnetically induced multiferroics.
