Abstract
Abstract Detailed Mossbauer effect and L III absorption spectroscopy experiments on a sample of EuPd 2 Si 2 are reported. A quantitative correlation of these two valence sensitive spectroscopies is made over the range of the thermally induced valence change of 0.51 electrons. The resulting relation between 151 Eu isomer shift and L III determined valence is used to provide a tentative estimate of the valence states of a number of other 1:2:2 Eu compounds and to emphasize the extent to which magnetic order and valence mixing coexists in such compounds.
