摘要：
The effect of the external hydrostatic pressure P approximate to 4 kbar on the relaxation of the normal electrical resistance of YB2Cu3O7-x single crystals with oxygen deficiency was investigated. It has been established that a high pressure significantly intensifies the process of diffusion coalescence of oxygen clusters, i.e. causes the growth of their average size. In turn, an increase in the size of oxygen clusters leads to the appearance of a phase, which is characterized by a higher critical temperature of the superconducting transition T-c.
