Zn doping of YBCO and hall effect study in Y1Ba2(Cu1-xZnx)3O7-δ

Long-exposure photographs taken with a Guinier camera on powders of Zn doped YBCO indicate incomplete inclusion of Zn in YBCO for x>=0.05. The study of the temperature dependence of the Hall number in Zn doped YBCO ceramics shows no substantial change of the number of carriers but the presence of Zn provokes the flattening of Hall number vs T.
