Abstract

We propose muSR study of oxygen spin polarization YMn2O5, and related compounds that exhibit multiferroic behavior. Recent study by resonant soft-x-ray diffraction has revealed that strong d-p hybridization and accompanying oxygen spin polarization may be the driving mechanism for the strong magneto-electric coupling in YMn2O5. MuSR would provide direct test for the occurrence of oxygen polarization as local probe.
