Hall effect in the perovskite manganites

We compute the zero-temperature phase diagram and Hall response of doped pe rovskite manganites within the model of double exchange and Jahn-Teller cou pling, employing the d-->infinity approximation proposed by Millis, Mueller , and Shraiman [Phys. Rev. B 54, 5389 (1996); 54, 5405 (1996)]. We find tha t in this scenario a "holelike" RH for the hole-doped manganites, as observ ed at low temperature by Matl et al. [Phys. Rev. B 57, 10248 (1998)], can b e obtained only when lattice distortions persist in the metallic state as T -->0. The calculated temperature dependence of RH seems to be consistent wi th the measured ''normal'' Hall coefficient in thin films. [S0163-1829(99)1 0503-3].
