Dynamic Jahn-Teller Effect and Colossal Magnetoresistance in La 1-x Sr x MnO 3
TLDR
A model which incorporates the physics of dynamic Jahn-Teller and double-exchange effects is presented and solved via a dynamical mean field approximation to reproduce the behavior of the resistivity and magnetic transition temperature observed in Sr_x MnO_3.Abstract:
A model for the doped rare-earth manganites such as ${\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{Sr}}_{x}{\mathrm{MnO}}_{3}$ 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.read more
