Abstract
In this paper, the influence of praseodymium doping on the conductivity across (transverse) the basal plane of high-temperature superconducting Y 1-x Pr x Ba 2 Cu 3 O 7-δ single crystals is investigated. It is determined that an increase of praseodymium doping leads to increased localization effects and the implementation of a metal–insulator transition Y 1-x Pr x Ba 2 Cu 3 O 7-δ, which always precedes the superconducting transition. The increase of the praseodymium concentration also leads to a significant displacement of the point of the metal–insulator transition to the low temperature region.
