Description

Local deviations of Y:Ba:Cu ratio from the stiochiometric value 16.7:33.3:50.0 in single-phase superconducting samples of Y1Ba2Cu3Osub(7-z) have been studied by EDXS in grains and grain boundaries. Two types of single-phase pellets, sintered from solution derived citrate complex and mechanically ground powders, are studied here. (author). 6 refs., 3 figs., 1 tab
