We investigate theoretically manganese oxides where the colossal magnetoresistance (CMR) is observed. Recent studies show that, if there are both an electron and a hole in the eg-band of Mn , the Jahn–Teller distortions split the band into a conduction band [Formula: see text] and a localized band [Formula: see text]. We find a Kondo lattice model with hole conduction in manganese oxides when the electron in the localized eg-band [Formula: see text] plays the role of the Kondo impurity. The Curie temperature (Tc) and the resistivity are calculated. We also calculate the antiferromagnetic temperature by a spin-Peierls transition.
