Abstract
The effects of structural with the isovalent chemical substitution of Ca2+ into the Sr2+ sites in new series of single perovskite La0.6(Sr0.4-xCax)MnO 3 compounds (x = 0 - 0.4) and double perovskites (Sr2. xCax)FeMoO6 (0 ≤ x ≤ 2.0) systems are investigated. The phase transformation from rhombohedral to orthorhombic and tetragonal to monoclinic by increasing the Ca content has been observed in the La0.6(Sr0.6-xCax)MnO3 compounds (x = 0 - 0.4) and (Sr2-xCax)FeMoO6 (0 ≤ x ≤ 2.0) systems, respectively. All the results demonstrate that the chemical pressure and chemical size play an important role in controlling the magnetoresistance in manganites.
