摘要
The angular dependence of the circular magnetic x-ray dichroism at the Dy LIII edge of the alloy Dy0.4Tb0.6 has been studied at T=80 K to ascertain the multipolar nature of the features in the dichroic spectra below the absorption edge. Angular behavior, consistent with quadrupolar transitions, is observed in the feature below the edge. We discuss the reasons for numerous recent failures to observe such an effect. © 1995 The American Physical Society.
