Inhomogeneous magnetism induced in a superconductor at superconductor-ferromagnet interface
We study a magnetic proximity effect at superconductor (S) ferromagnet (F ) interface. It is shown that due to an exchange of electrons between the F and S metals ferromagnetic correlations extend into the superconductor, being dependent on interface parameters. We show that ferromagnetic exchange field pair breaking effect leads to a formation of subgap bands in the S layer local density of st...
متن کاملBernoulli Equilibrium States for Surface Diffeomorphisms
Suppose f : M → M is a C1+α (α > 0) diffeomorphism on a compact smooth orientable manifold M of dimension two, and let μΨ be an equilibrium measure for a Hölder continuous potential Ψ : M → R. We show that if μΨ has positive metric entropy, then f is measure theoretically isomorphic mod μΨ to the product of a Bernoulli scheme and a finite rotation.
متن کاملTranslational correlations in the vortex array at the surface of a type-II superconductor.
We discuss the statistical mechanics of magnetic flux lines in a finite-thickness slab of type-II superconductor. The long wavelength properties of a flux-line liquid in a slab geometry are described by a hydrodynamic free energy that incorporates the boundary conditions on the flux lines at the sample’s surface as a surface contribution to the free energy. Bulk and surface weak disorder are mo...
متن کاملBallistic reflection at a side-gate in a superconductor-semiconductor- superconductor structure
We have fabricated a sub-micron-sized structure consisting of an InAs-based 2DEG, two narrow Nb leads and a gate, where the indirect ballistic transport between the non-oppositely superconducting contacts can be controlled by the voltage applied to the gate. This new kind of tuneable junction can be used for applications and allows several fundamental questions related to the transport mechanis...
متن کاملDetermining the vortex tilt relative to a superconductor surface
It is of interest to determine the exit angle of a vortex from a superconductor surface, since this affects the intervortex interactions and their consequences. Two ways to determine this angle are to image the vortex magnetic fields above the surface, or the vortex core shape at the surface. In this work we evaluate the field h(x,y,z) above a flat superconducting surface x,y and the currents J...
