Abstract

The present research is devoted to the cationic-deficient SrMoO₄-based sheelite-related complex oxides. The doping with bismuth to A sublattice and codoping with bismuth and vanadium (to A and B sublattices, respectively) were discussed. The X-Ray powder diffraction and infrared spectroscopy were used to investigate structural characteristics of the complex oxides. In
Sr_1-1.5xBi_xMoO₄, a superstructural ordering was observed. Conductivity and dielectric loss of ceramic samples are measured using alternating current.

Keywords
