Effect of irradiation with fast electrons on the anisotropy of the magnetoresistance in YBa2Cu3O7-δ single crystals
V.Karazin Kharkiv National University, 4 Svobody Sq., 61022 Kharkiv, Ukraine
In this work, we investigated the influence of the misorientation angle between the direction of the constant magnetic field H = 15 kOe and the direction of the basal ab-plane on the temperature dependences of the excess conductivity in the region of transitions to the superconducting state of YBa2Cu3O7-δ single crystals irradiated with fast electrons at T << 10 (energy 0.5-2.5 MeV, dose 1018 cm-2). It was determined that at temperatures T >> Tc, the temperature dependences of the excess paraconductivity are interpreted within the framework of the Aslamazov-Larkin theoretical model of the fluctuation conductivity for layered superconducting systems. The reasons for the appearance of low-temperature "tails" (paracoherent transitions) on resistive transitions corresponding to different phase regimes of the vortex matter are discussed.
