چکیده انگلیسی
The influence of irradiation by electrons with energies of 0.5 ⦠2.5â¯MeVâ¯at temperatures of about 10â¯K on the basal-plane resistivity of the YBa2Cu3O7âδ single crystals is investigated in the range from Tc to 300â¯K. The resistivity temperature dependence is determined by defects arising due to the irradiation. These defects directly affect the superconducting transition, decreasing Tc and increasing the transition width without significant distortions of its shape. The resulting defects also lead to an increase in the Debye temperature due to a reduction of the anisotropy, and a noticeable increase in the scattering by phonons in the sample. The excess conductivity does not change with the irradiation used.
