摘要：
Using the Kondo lattice model with classical spins in infinite dimension, conductivity in the perovskite-type 3d transition-metal oxide (La, Sr)MnO3 is theoretically studied. Green's functions as well as spontaneous magnetization are obtained exactly on the Bethe lattice as a function of temperature. Conductivity is calculated from the Kubo formula. Below the Curie temperature, resistivity as a function of magnetization is in good agreement with the experimental data. Anomalous behavior in the temperature dependence of the optical conductivity observed in (La, Sr)MnO3 is also explained.
