Abstract

In this paper, we investigate the temperature dependence of the transverse conductivity in Y 1-z Pr z Ba 2 Cu 3 O 7-δ single crystals with different praseodymium concentrations. It is determined that the increase of the praseodymium concentration in Y 1-z Pr z Ba 2 Cu 3 O 7-δ leads to the enhancement of localization effects. This in turn results to the transition from the pseudo-gap regime to the variable-range-hopping regime.
