Desarrollo analítico de las ecuaciones Ginzburg-Landau parapelículas delgadas superconductoras en presencia de corrientes

Abstract

An analytical analysis to obtain the time dependent Ginzburg- Landau equations in presence of a current J and magnetic field H in a mesoscopic superconducting thin film is shown. The transport current is applied in a little contact in the boundary of the sample. This contacts are included through to the deGennes extrapolation parameter b in the boundary conditions. Finally, we show a useful tool that can be used to found the evolution of ψ(A,t) in this formalism. We found the dependence of the magnetization M(H) and magnetic susceptibility χ m (H) with b for such sample.
