Abstract

barium compounds

high temperature superconductors

nuclear magnetic resonance

yttrium compounds

We report the first observation of 17O NMR spectra in YBa 2Cu3O7 obtained after selective gas exchanges performed at 300 and 850°C. We are able to assign the narrow (weakly shifted) signal to the (1/2, - 1/2) transition of oxygen atoms in CuO chains and the broad (strongly shifted) signal to the 0-sites in CuO2 planes.
