Кристаллическая структура и свойства сложных оксидов, образующихся в системе Ba–Pr–Fe–Co–O

Abstract

The complex oxides Ba1-xPrxFe1-yCoyO3-δ were synthesized using a glycerol-nitrate technology. The crystal structure of the all single-phase samples was identified as cubic (Pm3m space group). The values of oxygen content in the samples were determined using a high temperature thermogravimetric analysis and iodometric titration. Total conductivity and Seebeck coefficient of complex oxides were measured using a 4-probe technique as a function of oxygen partial pressure.
