| contents | The Role of the Boundary Conditions on the Critical Properties of Superconducting Rings Under the Action of a Tranversal Magnetic Field J. M. Calero J. C. Granada N. Porras-Montenegro Física, Astronomía y Matemáticas Landau Ginzburg Superconducting rings In the framework of the Ginzburg-Landau (GL) theory in the limit of a GL parameter much larger than unity,we study theoretically the critical behavior of a mesoscopic superconducting ring with negligible width in thepresence of a magnetic field applied perpendicularly to the ring plane. It is assumed that the inner ring edge is incontact with a material whose properties are accounted in the de Gennes boundary condition with a parameterb (de Gennes extrapolation length), while the outer edge is in contact with vacuum. Special attention is devotedto the influence of the different materials contacting the inner ring edge of the superconductor on the features ofthe phase diagram, as well as the effect of the confinement on such thermodynamic property. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436536 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36 |
