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

Colossal Magnetoresistance Observed in Monte Carlo Simulations of the One- and Two-Orbital Models for Manganites
TL;DR: In this article, the one-and two-orbital double exchange models for manganites are studied using Monte Carlo computational techniques in the presence of a robust electron-phonon coupling, but neglecting the antiferromagnetic exchange between the localized spins.

Effect of strain and tetragonal lattice distortions in doped perovskite manganites
TL;DR: In this paper, a series of coherently strained manganite superlattices with laser molecular beam epitaxy was presented. But the effect of biaxial strain and Jahn-Teller-type lattice distortions was not considered.
