Giant paramagnetic Meissner effect in multiband superconductors
Superconductors, ideally diamagnetic when in the Meissner state, can also exhibit paramagnetic behavior due to trapped magnetic flux. In the absence of pinning such paramagnetic response is weak, and ceases with increasing sample thickness. Here we show that in multiband superconductors paramagnetic response can be observed even in slab geometries, and can be far larger than any previous estima...

متن کاملAndreev spectra and subgap bound states in multiband superconductors.
A theory of Andreev conductance is formulated for junctions involving normal metals (N) and multiband superconductors (S) and applied to the case of superconductors with nodeless extended s(+/-)-wave order parameter symmetry, as possibly realized in the recently discovered ferropnictides. We find qualitative differences from tunneling into s-wave or d-wave superconductors that may help to ident...
متن کاملPropagating normal domains in large composite superconductors
We study the nucleation and propagation of the normal zone in large composite superconductors, considering the relatively long time of current redistribution in the stabilizer. We propose a model treating the composite as an effective electrical circuit, which yields two diffusion equations for the electric current and temperature distributions along the conductor. Numerical simulations are per...
متن کاملRectangular normal domains in current-carrying superconductors
We find a type of normal domain in composite superconductors—a traveling rectangular domain. Using the effective circuit model we study in detail the dynamics of this domain. We derive an analytical solution for the propagation velocity and the length of a traveling rectangular domain. Current–voltage characteristics are calculated for a superconductor with a rectangular domain. © 1998 American...
