Effect of pre-strain on the flux dynamics of current-carrying superconductors containing defects

This article presents a study that combines the electrostatic potential equation with the time-dependent Ginzburg-Landau equation, incorporating volume strain and utilizing Maxwell-type and current-carrying boundary conditions. Through the finite difference method, the research investigates the magnetic flux dynamics and energy variations in a type II superconductor with an artificial defect at the center, considering pre-strain, external magnetic field, and external current. The findings indicate that linear deformation and external electric field have a significant impact on the electrical properties, distribution of magnetic flux vortices, vortex dynamics, order parameter value, and overall total energy in superconductors with defects. These results contribute to a better understanding of the magnetic flux dynamics in superconductors under complex conditions.
