Figure 7From: Metal-insulator transition and electroresistance in lanthanum/calcium manganites La1-xCa x MnO3 (x= 0–0.5) from voltage-current-temperature surfacesLa 0.7 Ca 0.3 MnO 3 voltage surface. The voltage across the sample is shown on the vertical axis as a function of the applied current and the temperature.Back to article page
