摘要：

La0.8Sr0.2MnO3 (LSMO) powders were successfully synthesized by three routes (sol-gel, spray dryer and conventional solid state method). The precursors were characterized by particle size analysis, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The sintering stage of all powders was also investigated by dilatometer. Finally, the sintered LSMO ceramics have been investigated magnetically and electrically in view to study the ferromagnetic-paramagnetic and/or metal-insulator transition. The magnetoresistance MR up to 42% above room temperature has been observed. (C) 2004 Elsevier SAS. All rights reserved.
