摘要：
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 alpha angle(H, ab) on the temperature dependences of the excess conductivity in the region of transitions to the superconducting state of YBa2Cu3O7-delta single crystals irradiated with fast electrons at T< 10 K (energy 0.5 divided by 2.5 MeV, dose 10(18) cm(-2)). It was determined that at temperatures T > T-c, 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.
