Abstract

The Mössbauer effect of the 37.2 keV γ transition of ¹²¹Sb has been employed to study the electronic configuration of Sb ions in perovskite superconducting materials. The isomer shift (IS) changes with Sb content and falls in the region of the Sb(V) valence state. The IS increases from 7.00 mm/s for BaPb_0.75Sb_0.25O₃ to 7.25 mm/s for BaPb_0.75Bi_0.25O₃ and to 7.70 mm/s for (Ba_0.6K_0.4)BiO₃ compounds, indicating a high degree of covalency, corresponding to changes in the 5s^m5p ⁿ hybridization.
