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

TL;DR: In this article, the low temperature magnetic circular dichroism (MCD) and X-ray absorption fine structure (XAFS) spectra have been interpreted in terms of the Cu(II) centers distorting the host lattice such that the CuO6 center is a tetragonally elongated octahedron.

Electrical and magnetic properties of perovskite at low temperature
TL;DR: In this article, the authors investigated the magnetic and electrical properties at low temperature down to 1.8 K and found that magnetic susceptibility and magnetoresistance increase with the increase of x. The increase in magnetic susceptibility is due to reduction in Mn-O-Mn bond angle and the mobility of charge carriers.
