Dynamic Jahn-Teller Effect and Colossal Magnetoresistance in $L a_{1 - x} A_{x} M n O_{3}$

Abstract

A model for $L a_{1 - x} S r_{x} M n O_{3}$ which incorporates the physics of dynamic Jahn-Teller and double-exchange effects is presented and solved via a dynamical mean field approximation. In an intermediate coupling regime the interplay of these two effects is found to reproduce the behavior of the resistivity and magnetic transition temperature observed in $L a_{1 - x} S r_{x} M n O_{3}$ .
