摘要
We report a giant resistance drop induced by dc electrical currents in La0.67Ca0.33MnO3 epitaxial thin films. Resistance of the patterned thin films decreases exponentially with increasing current and a maximum drop shows at the temperature of resistance peak T-p. Variation of resistance with current densities can be scaled below and above T-p, respectively. This work can be useful for the future applications of electroresistance.
