Abstract
The conditions for the occurrence of reentrant superconductivity in granular superconductors are studied. The parameters of synthesis of the ceramic samples of CaLaBaCu3Ox, SrLaBaCu3Ox and YBa2–xSrxCu3OySez compositions, the results of their microstructure research, the elemental composition and the temperature dependence of the resistance are given. Samples are obtained, which reproducibly exhibit the reentrant superconductivity after the tens of thermal cycling. The relationship between the occurrence of reentrant superconductivity and the oxygen content in the samples was not established.
