Resistivity properties of the mixed-phase manganite La0.96Te0.04MnO3

Based on the phase separation scenario, the resistivity of La0.96Te0.04MnO3 is investigated by using the random network model. The good quantitative simulated results reveal that the magnetic field-induced change results in the resistivity reduction and the colossal magnetoresistance. Assuming a thermal hysteresis of magnetization, our approach yields a reasonable prediction of thermal hysteresis of resistivity.
