Abstract
We have investigated the resistivity, the Hall number, n(H), and the H all conductivity, sigma(H), in bulk YBa2 (Cu1-xZnx)3O7-delta within th e range of Zinc content 0<x<0.06. The magnetic field values were up to 5 T and the temperature range 20 K-300 K. The superconducting transit ion temperature Tc, as well as, the slope of the normalized resitivity in the normal-state decrease with increasing Zn concentration. The T3 dependence of sigma(H)-1, with a change of the slope around 230 K-240 K is correlated with the T-dependence of the carrier concentration.
