Electronic structure of Sb in BaPb sub 1 minus x Sb sub x O sub 3 superconducting compounds
Abstract
The Moessbauer effect of the 37.2 keV {gamma} transition of {sup 121}Sb has been employed to study the electronic configuration of Sb ions in BaPb{sub 1{minus}{ital x}}Sb{sub {ital x}}O{sub 3} superconducting materials. The isomer shift is constant as a function of Sb content and falls in the region correspoding to the Sb(V) valence state. The isomer shift of 7 mm/s is the lowest value yet observed for an Sb(V)O{sub 6} chromophore and indicates a high degree of covalency, corresponding to significant 5{ital s}{sup {ital m}} 5{ital p}{sup {ital n}} hybridization. The mixed valence state of an equal amount of Sb(III) and Sb(V) has not been observed.
