Resumo
A nanoparticles of La1-xSrxMnO3 were synthesized using homogenous coprecipitation method. The precipate was washed with water and dried at 80 °C. The samples were characterized by X-ray powder diffraction, transmission electron microscopy (TEM) and electrical resistivity as a function of temperature. The TEM results show that the particle size is in the nanometer scale.
