Abstract
Cu K-edge XANES spectroscopy has been used to study local structure around the Cu-site in three-dimensional oxygen deficient perovskite La8-xSrxCu8O20 system. The combination of E//ab and E//c polarization and high resolution XANES spectra on high quality single crystals has allowed us to distinguis h the various features associated with the complex Cu-O networks in the sys tem which have then been compared with those of the La2-xSrxCuO4 system.
