摘要

We have investigated the crystal structure and magnetic properties of the new series of ordered double perovskite oxides (Sr2-xCax)FeMoO6 (0≤x≤1.0). A monotonous decrease of the lattice constants (a and c) has been found with increasing x. Such an effect may also give rise to a distorted structure with Fe-O-Mo angle changing from 180° for x = 0 to 162° for x = 1.0. The magnetization increases from x = 0 to 0.5 and then slightly decreases from x = 0.5 to 1.0. Such complex magnetic behavior is strongly correlated to the chemical size effect (corresponding to the internal pressure) in the title compounds.
