摘要：
In the present study influence of praseodymium doping on conductivity across (transverse) the basal plane of high-temperature superconducting Y1-xPrxBa2Cu2O7-delta single crystals is investigated. It is determined that increase of praseodymium doping leads to increased localization effects and implementation of the metal - insulator transitionY(1-x)Pr(x)Ba(2)Cu(3)O(7)(-)(delta), which always precedes the superconducting transition. The praseodymium concentration increase also leads to significant displacement of the point of the metal - insulator transition to the low temperature region.
