Abstract

A model for the doped rare-earth manganites such as ${La}_{1 - x} {Sr}_{x} {MnO}_{3}$ incorporating the physics of dynamic Jahn-Teller and double-exchange effects is presented and solved via a dynamical mean field approximation. The interplay of these two effects as the electron phonon coupling is varied reproduces the observed behavior of the resistivity and magnetic transition temperature.
