Fractional vortices and a Bean-Livingston barrier in two-component superconductors | M.A. Silaev
; | Date: |
6 Aug 2010 | Abstract: | In the framework of London theory we show that fractional vortices in
two-component superconductors can be stabilized near the surface. Consequently
the process of vortex entry into the superconductor consists of several steps,
while the external magnetic field increases from zero. At the first stage only
vortices in one of the order parameter components penetrate and sit at the
equilibrium position near the surface. When the magnetic field is increased
further vortices in the second order parameter component eventually enter the
superconductor. Such a complex partial vortex penetration leads to the
modification of a Bean-Livingston barrier and a magnetization curve as compared
to conventional single-component superconductors. | Source: | arXiv, 1008.1194 | Services: | Forum | Review | PDF | Favorites |
