Essay

The dissertation is devoted to the investigation of fundamental electronic processes and interactions which form the normal and superconducting (SC) phase in high-temperature superconductors YBa2Cu3O7-d, both by changing the level of doping with oxygen, and applying hydrostatic pressure up to 1 GPa, as well as in compounds of the Y1-xPrxBa2Cu3O7-d and YBa2Cu3O7-d - PrBa2Cu3O7-d type, when the content of the magnetic atoms of Pr and layers of PrBa2Cu3O7-d is changed to obtain information about the physical nature of the interplay between superconductivity and magnetism. The basic mechanism of the interplay between the superconducting fluctuations and magnetism is identical in the magnetic superconductors that we have studied.
