We have conducted a systematic 57 Fe MoK ssbauer study on BaR(Cu 0.5 Fe 0.5 ) 2 O 5؉ double perovskites with various oxygen contents and rare-earth elements (R ‫؍‬ Lu, Yb, Y, Eu, Sm, Nd, and Pr). In samples based on R ‫؍‬ Lu, Yb, Y, Eu, Sm the oxygen content remained at +0, upon reductive or oxidati
