摘要：

The aim was to conduct comparative studies of the evolution of conductivity along and across the base ab plane in Y 1 - z P r z B a 2 C u 3 O 7 - delta single crystals at different degrees of praseodymium doping in a wide range of concentrations 0 & LE; z & LE; 0.5. It is established that the increase in the degree of praseodymium doping in samples Y 1 - z P r z B a 2 C u 3 O 7 - delta leads to increased effects of localization and implementation in the system of metal-insulator type transition, which always precedes the superconducting transition. Increasing the concentration of praseodymium leads to a significant shift in the beginning of the metal-insulator transition at the low temperature region.
