| Abstract |
We have used polarized Cu K-edge extended x-ray absorption fine structure to investigate the local lattice displacements in the charge-ordered La1.48Nd0.4Sr0.12CuO4 system. The temperature-dependent distance broadening, given by the Debye-Waller factors of the Cu-O bonds measuring local lattice fluctuations, shows a clear steplike increase below the charge stripe order temperature. The results construct a direct evidence for the local lattice fluctuations as a response function of the charge stripe ordering in the cuprate superconductors.
