Abstract

The effects of structural with the isovalent chemical substitution of Ca²⁺ into the Sr²⁺ sites in new series of single perovskite La^0.6(Sr_0.4-_xCa_x)MnO ₃ compounds (x = 0 - 0.4) and double perovskites (Sr₂. _xCa_x)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 La_0.6(Sr_0.6-xCa_x)MnO₃ compounds (x = 0 - 0.4) and (Sr_2-xCa_x)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.
