Abstract

We compute the zero-temperature phase diagram and Hall response of doped perovskite manganites within the model of double exchange and Jahn-Teller coupling, employing the (Formula presented) approximation proposed by Millis, Mueller, and Shraiman [Phys. Rev. B 54, 5389 (1996); 54, 5405 (1996)]. We find that in this scenario a “holelike” (Formula presented) for the hole-doped manganites, as observed at low temperature by Matl et al. [Phys. Rev. B 57, 10 248 (1998)], can be obtained only when lattice distortions persist in the metallic state as (Formula presented) The calculated temperature dependence of (Formula presented) seems to be consistent with the measured “normal” Hall coefficient in thin films.
