Abstract
The effect of the Cu substitution by Cc in the ''2223'' superconductor was studied by resistivity and Hall effect measurements. The excess c onductivity was analyzed by using the linear and Zou-Anderson extrapol ation methods on the electrical resistivity. A crossover temperature i s observed only for the x = 0 sample. The sheet hole concentration per Cu-site, n(H)V(cell) is found to vary linearly with the temperature f or all Cr doped samples in the 170-265 K temperature range. Deviations from linearity in the T-2 dependence of the inverse Hall mobility abo ve 250 K were evidenced.
