Abstract
Nanopolycrtstalline La2/3Sr1/3MnO3 ceramics were prepared using nanosized precursor powders. Highly nonlinear current–voltage characteristics were observed at room temperature and low temperature. The nonlinearity coefficient is in the range of 1.15–53.5. The electroresistance (ER) and magnetoresistance (MR) effects have been investigated. The magnetoresistance of all the samples shows strong dependence on sintering temperature. Magnetoresistance decreases with increasing temperature.
