“…Several works have been done on vortex configuration with structural or topological defects in superconducting thin films, finding that superconductor/dielectric boundary conditions lead to the well known Beam-livingston surface barrier, which is responsible for the hysteresis in the magnetization curve. In turn, a superconducting/ superconducting interface or temperature gradients increase the transition field Hc2 [4] - [7]. The effect of the extrapolation length of deGennes b on the critical temperature Tc for various sample geometries was studied by Fink et al They found that the parameter of deGennes can be used to describe a reduction of Tc in small superconductors [8].…”

“…Other authors found that Tc can be modified by applying electric field in a reversible way [9] - [11]. To study the effect of topological defects on the superconducting state, we solve the Ginzburg-Landau time-dependent equations (TDGL) in a mesoscopic square where the temperature T is modified locally within the sample as T(x,y)=δRandom, where δ is a constant that identifies the maximum intensity of the generated numbers and Random is a function that takes random values between 0 and 1, (see references [2] and [7]). The paper is organized as follows: in section 2, we write the dimensionless TDGL equations in an invariant zero gauge form using the auxiliary field in Cartesian coordinates.…”
