Experimental studies of local structure by pulsed neutron PDF analysis on manganites and cuprates suggest that these oxides are locally distorted due to a strong electron-lattice interaction, and charge carriers organize themselves most likely into a tweed-like state. Measurements by inelastic neutron scattering as well as calculations on the Hubbard model show that the electron-lattice interaction is strongest at the zone boundaries, enhanced by phonon-induced spin-correlations. Such a strong electron-lattice interaction must be the origin of these local distortions, and may form the basis for the microscopic mechanism of superconductivity.
