Abstract
Stoichiometric local characterizations of YBaCuO oxides have been perf ormed using a 1.4 MeV deuteron microbeam. A beam with a size of 10 x 1 5 mu m(2) allows the observation of variations of x = 0.2 in sintered YBa2Cu3O7-x. Local variations of oxygen stoichiometry in a melt-textur ed sample, correlated with the microstructure, have been observed. In spite of the degradation of the sample under the beam, oxygen measurem ents seem to remain significant for doses above 10(18) ions/cm(2).
