Abstract

The structural, electrophysical, and magnetic properties of high-temperature superconducting Gd_{1 + x}Ba_{2 - x}Cu₃O_{7 - δ} (0<x<0.38) ceramics are investigated experimentally. As x increases, the first critical field and the temperature of the superconducting transition decrease, while the width of the transition increases. The variation of T_c(x) resembles curves obtained previously for KE_{1 + x}Ba_{2 - x}Cu₃O_{7 - δ} compounds (RE = Nd, Eu, Sm). Some possible ways in which the substitution of Gd^{3 +} for barium influences the electronic structure and population of various sites with oxygen atoms are discussed; these factors suppress superconductivity in the given compounds.
