The measurement of the Cu-O distances by a local and fast probe, polarized Cu K-edge extended x-ray absorption fine structure (EXAFS) in La1.85Sr0.15CuO4 crystal shows two different conformations of the CuO6 octahedra below 100 K assigned to two types of stripes with different lattice. This experiment supports a model of `'two components'' spatially separated in a superlattice of quantum stripes for the anomalous properties of cuprate superconductors.

Abstract
The measurement of the Cu-O distances by a local and fast probe, polarized Cu K-edge extended x-ray absorption fine structure (EXAFS) in La1.85Sr0.15CuO4 crystal shows two different conformations of the CuO6 octahedra below 100 K assigned to two types of stripes with different lattice. This experiment supports a model of `'two components'' spatially separated in a superlattice of quantum stripes for the anomalous properties of cuprate superconductors.File in questo prodotto:
