Abstract |
Theoretical analysis is presented of the influence on the current-voltage characteristics of the nanosized
defects, which may be created by heavy ions irradiation or can arise in technological process, for instance
during the winding procedure of the superconducting coil. Results of calculations, performed basing
on developed model of the interaction of pancake type vortices appearing in HTc superconductors with
nano-sized defects are presented. The energy balance for flux creep process is deduced and current-voltage
characteristics calculated in the function of static magnetic field, in accordance with experimental behavior.
This static analysis has been extended further on the case of the time-varying magnetic field in which
existence of dynamical anomalies is predicted, according to our previous experimental data.
