We have found that the 77-K magnetization per formula unit of the SrFeO3 − δ ferrite, Sr0.9La0.1Fe0.9Cd0.1O3 − δ and Sr0.75La0.75Fe0.75Cd0.75O4 − δ mixed oxides, and SrLaFeO4 compound, calculated per mole of Fe ions, is 0.114μB, 0.024μB, 5 × 10−3 μB, and 4.3 × 10−2 μB, respectively. The resultant effective magnetic moment of the Fe3+ and Fe4+ ions $(\mu _{effFe^{3 + } ,Fe^{4 + } } )$ in the Sr...
Cobaltites-gallates in the binary system LaCoO3 – LaGaO3 are synthesized. X-ray phase analysis showed that a continuous series of solid solutions with the composition LaCo1 − xGaxO3 is formed in the system investigated. It is determined that solid solutions with 0 < x ≤ 0.7 and 0.7 < x ≤ 1.0 possess rhombohedrally and orthorhombically distorted perovskite structure, respectively. Analysis...
