FIG. 1.

Temperature dependence of resistance for LCMO under different dc currents. From top to bottom, , 0.01, 0.05, 0.1, 0.2, 0.5, 1, 2, 3, 4, 5, and 6 mA, respectively. The upper inset shows that the warming up and cooling down measurements are consistent. The lower inset is the scheme of the patterned film. The four grey rectangle parts are deposited gold for contact and the black parts are the patterned LCMO films. The size of the sample is and the size of the LCMO bridge is .

FIG. 2.

Temperature dependence of resistance for LCMO under different dc currents for sample with severe heating effect. (a) Temperature dependence of electroresistance for LCMO under different dc currents without the influence of heating effect (from Fig. 1). (b) Variation of the peak resistance with dc current density (from Fig. 1).
