摘要：

The effect of hydrostatic pressure up to 25 kbar on the temperature of superconductive transition and the critical field of irreversibility for YBa2Cu4Ox and YBa2Cu3.5Ox single crystals was investigated. The critical parameters increase under pressure and the anisotropy of the critical field of irreversibility decreases for both phases. The large value of the dTc/dP derivatives may be accounted for by the structural peculiarities of the superconductors under consideration. © 1990.
