The structural, magnetic, and nonstoichiometric properties of the perovskite-like Pr 1؊x Sr x CoO 3؊ phase (04x40.80) have been studied by powder X-ray and neutron di4raction and magnetic susceptibility measurements between 5 and 295 K as well as by redox titration. In the compostion range 04x40.30
Crystal structure, redox, and magnetic properties for the Pr 1؊x Sr x FeO 3؊ solid-solution phase have been studied. Oxidized samples (prepared in air at 9003C) crystallize in the GdFeO 3type structure for 04x40.80, and probably in the Sr 8 Fe 8 O 23type (unpublished) structure for x ؍ 0.90. Reduc
