Effects of electron irradiation on irreversibility line in superconducting YBa2Cu3O7

Abstract
The authors have investigated the effects of 2.5 MeV electron irradiation on the irreversibility line of a sintered YBa2Cu3O7 by applying DC and AC measuring techniques. They find that after electron irradiation, both the superconducting transition temperature Tc and the irreversibility temperature Tirr, determined by either technique, decrease; the decrease in Tirr scales with the decrease in Tc.
