摘要：
The effect of high hydrostatic pressure up to 10 kbar on the electrical resistance in the basic ab- plane of praseodymium-doped (x approximate to 0.34) single crystals Y1-XPrXBa2Cu3O7-delta was investigated in the work. It was found that, in contrast to samples with a praseodymium content of x approximate to 0.05, the application of high pressure leads to a multiple increase in the value of the baric derivative dTc/dP. It was established that within the limits of experimentally achieved pressures, there was no change in the sign of baric derivatives dTc/dP with increasing pressure, which was observed on polycrystalline samples with close values of praseodymium concentration. Possible mechanisms of influence of high pressure on Tc are discussed, taking into account peculiarities in the electronic spectrum of carriers.
