Manganese perovskites of the CaSbxMn1-xO3 (x=0.1, 0.2, 0.25, 0.33, 0.5) family have been synthesized by solid state reactions and structurally characterized by Rietveld refinement of the powder X-ray diffraction data. CaSb0.1Mn0.9O3 crystallizes in Pnma space group with a GdFeO3-type orthorhombic structure, whereas the other members of the series crystallize in the space group P21/m. Unit cell volumes of these members increase linearly with antimony content. Divergences between ZFC and FC magnetic susceptibilities were observed for CaSb0.1Mn0.9O3, CaSb 0.33Mn0.67O3 and CaSb0.5Mn 0.5O3 at low temperatures. Antiferromagnetic transitions at 125K and 113K were found for CaSb0.2Mn0.8O3 and CaSb0.25Mn0.75O3, respectively. © 2003 Elsevier Inc. All rights reserved.
