摘要：
The ordered double perovskite Ba-2 FeMoO6 has been prepared by solid-state reaction, and investigated by means of the magneto resistance (MR) and field-dependent magnetization. The temperature dependence of resistivity shows metallic behavior below the ferromagnetic transition temperature, The magnitude of MR is as large as - 5% with the magnetic field of 0.8 T at room temperature. A qualitative analysis of the observed MR is attempted through a correlation between MR and magnetization. (C) 2001 Elsevier Science B.V. All rights reserved.
