| 中文摘要 | Double perovskite compounds (Sr2-xEux)FeMoO6 (0 <= x <= 0.3) were prepared by solid-state reaction at high temperature. Crystal structure, magnetic and transport properties of the compounds were investigated. The crystal structure of the compounds changes from an 14/m lattice to an Fm (3) over barm lattice around x=0.1. The unit-cell volume decreases with the doping level in both the 14/m lattice and the Fm (3) over barm lattice. The resistivity of the compounds shows a metal semiconductor transition, and the transition temperature TM-S increases with the doping level. However, Curie temperature (T-C) of the compounds exhibits a weak dependence on the doping level. The saturation magnetization (M-5) at 100 K varies almost linearly with the anti-site defect concentration and agrees well with the simple FIM model. In contrast to the Ce-, Pr-, Nd- and Sm-doped Sr2FeMoO6, the difference of M-S of (Sr2-xEu)FeMoO6 between 5 and 100 K indicates that the moment of Eu3+ is antiparellel to that of Fe3+ at low temperature.
