Abstract
A theoretical model is proposed for the (0,0,1) superlattice manganite system ${({\text{LaMnO}}_{3})}_{n}{({\text{SrMnO}}_{3})}_{m}$. The model includes the electron-electron, electron-phonon, and cooperative Jahn-Teller interactions. It is solved using a version of the single-site dynamical mean-field approximation generalized to incorporate the cooperative Jahn-Teller effect. The phase diagram and conductivities are calculated. The behavior of the superlattice is found to be a good approximation to be an average over the density-dependent properties of individual layers, with the density of each layer fixed by electrostatics.
