摘要
The double perovskite LaKFe1.2Mo0.8O6 ceramics have been successfully synthesized. The structure, magnetic and transport properties of this compound have been studied. Its structure belongs to cubic system with space group Fm (3) over barm. Magnetization slowly reduced with temperature and large magnetoresistance of the sample under LOT magnetic field remains constant around 0.95 in the studied temperature range. Magnetic field dependence of magnetoresistance is described and magnetoresistance increases abruptly under 0.65 T. The electrical transport properties can be described by the thermally activated hopping mechanism. (c) 2006 Elsevier B.V. All rights reserved.
