- Effect of a superconducting defect on the Cooper pairs of a mesoscopic sample Sindy Jessenia Higuera-Agudelo Heli Barba-Molina José José Barba-Ortega Ingeniería Landau Ginzburg Mesoscopics Square hole Superconducting We investigate the vortex state in a very long prism of square cross section with a central square defect in the presence of an external perpendicular magnetic field. We considered that the inner defect edge is in contact with a thin superconducting layer at higher critical temperature and/or with a dielectric material, while the outer edge of the sample is in contact with the vacuum. We have evaluated the superconducting order parameter, magnetization and vorticity as a function of the size of the defect at the first vortex penetration field. Therefore we conclude and we are able to show that circular geometry of the vortices near to the defect is mildly modified by the enhanced superconductivity at the edge of the hole. 2014 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49631663014 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.186 Vol.81
