摘要：
By using a combined model of the double exchange and the electron-phonon interaction, we have studied the colossal magnetoresistance phenomena observed in perovskite manganese oxides. We evaluate the resistance and the magnetoresistance by using the Kubo formula, and examine the crossover as a function of temperature. We also explore effects of the double-exchange interaction on the lattice degree of freedom.
