Abstract

The temperature-dependent amplitude of the Cu-O(planar) bond modulation in the La2CuO4.1 superconducting crystal has been measured by in-plane-polarized Cu K-edge extended x-ray-absorption Pine structure. Minority domains characterized by a long Cu-O(planar) bond length are found at T < 150 K. The separation between the two Cu-O(planar) distances provides a measure of the amplitude of the CuO2 lattice modulation assigned to a charge-density wave that coexists with the superconducting phase, providing evidence for a broken symmetry.
