A superconductor ceramic oxide with the Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub 7-//sub x/ phase and exhibiting a transition temperature at T/sub c/approx. =92 K, was irradiated at room temperature with 1 MeV electrons. It was found that the irradiation produces a sharp drop in the T/sub c/ value from 92 K down to approx. 40 K. The irradiated sample suffered a change from metallike character to semiconductorlike behavior at T>T/sub c/. It is also shown that after irradiation the twin boundaries on the material become irregular.
