摘要

The effect of electron irradiation with incident energy (E ≤ 40 keV) lower than the threshold for displacement of in-plane atoms on T_c, resistivity and Hall coefficient has been studied on fully oxygenated YBa₂Cu₃O_7-δ tin films. In contrast to the known T_c suppression at high-energy particle irradiation, an increase in T_c has been found as well as a factor of two increase in both the T-linear resistivity slope and the Hall coefficient as a function of radiation fluence. It has been shown that the changes observed in transport properties can be explained as being caused by disruption of the conductivity of CuO chains by radiation-induced chain oxygen defects.
