Nanoparticle synthesis of La/sub 1-x/Sr/sub x/MnO/sub 3/ (0.1, 0.2 and 0.3) perovskites

Synthesis of La/sub 1-x/Sr/sub x/MnO/sub 3/ (x=0.1, 0.2 and 0.3) by homogenous coprecipitation method using urea as precipitant agent is reported. The particles are smaller than 200 nm after heating at 950/spl deg/C. Temperature dependence of the electrical resistivity was found to be similar to the reported value for single crystals of these manganites.
