| 中文摘要 | Electron doped double perovskite compound (Sr2-xSmx)FeMoO6 (0 <= x <= 0.25) has been synthesized by solid-state reaction at high temperature. Crystal structure and magnetic properties of the compounds have been investigated by X-ray powder diffraction (XRD) and magnetic measurements. XRD revealed that all the compounds were of single phase and belonged to a 14/m lattice. The degree of cationic ordering on the B site was decreased pronouncedly by the electron doping. Different from the results of La- and Nd-doped Sr2FeMoO6, Curie temperature (T-C) of (Sr2-xSmx)FeMoO6 decreased first with the doping and then increased beyond x=0.15, indicating that steric effect was enhanced as the radius of rare-earth ions decreased. Saturation magnetization (M-S) of the compounds decreased with the doping level and anti-site (AS) concentration. Sm moment showed a considerable contribution to M-S at low temperature, leading to an abrupt drop of M-S between x=0.1 and 0.15. (C) 2009 Elsevier B.V. All rights reserved. |
