In this work, we present the study of structural, magnetic and critical behavior of La1−xSrxCoO3 (x = 0.3 and 0.5) cobaltites. X-ray diffraction analysis using the Rietveld refinement shows that the sample La0.7Sr0.3CoO3 crystallizes in a rhombohedral distorted perovskite structure with R 3 ¯ c space group, while La0.5Sr0.5CoO3 exhibits both phases rhombohedric and cubic,...
