Abstract

A superconductor ceramic oxide with the Y1Ba2Cu3O7−x phase and exhibiting a transition temperature at Tc ≍92K, was irradiated at room temperature with 1 MeV electrons. It was found that the irradiation produces a sharp drop in the Tc value from 92 K down to ∼40K. The irradiated sample suffered a change from metallike character to semiconductorlike behavior at T > Tc. It is also shown that after irradiation the twin boundaries on the material become irregular.
