Abstract
Nonlinear and hysteretic current–voltage characteristics and electric-pulse-induced resistance (EPIR) switching effects were found in Nd0.7Sr0.3MnO3 ceramics. For samples measured using the two-wire method, a polarity-dependent, stable and reproducible EPIR effect occurs in the whole temperature range measured. The high and low resistive metastates vary with temperature and seemingly can be destroyed by temperatures larger than 400 K. However, for the same sample measured using the four-wire method, no EPIR effect is observed. The result indicates that the EPIR effect is intensively correlated with the interface between the Ag-electrodes and the bulk of the Nd0.7Sr0.3MnO3 polycrystal.
