Properties of mesoscopic superconducting thin-film rings: London approach
نویسندگان
چکیده
Superconducting thin-film rings smaller than the film penetration depth ~the Pearl length! are considered. The current distribution, magnetic moment, and thermodynamic potential F(H ,N ,v) for a flat, washer-shaped annular ring in a uniform applied field H perpendicular to the film are solved analytically within the London approach for a state with winding number N and a vortex at radius v between the inner and outer radii.

We report on a scanning superconducting quantum interference device microscope operating at temperatures down to 20 mK in a dilution refrigerator. The instrument is designed for studying quantum mechanical coherence effects in mesoscopic systems and investigating magnetic effects on a mesoscopic length scale in novel materials. We have demonstrated the low-temperature operating capabilities of ...
متن کاملA Hierarchy of Models for Superconducting Thin Films
A hierarchy of models for type-II superconducting thin films is presented. Through appropriate asymptotic limits this hierarchy passes from the mesoscopic Ginzburg-Landau model to the London model with isolated vortices as δfunction singularities, to vortex-density models and finally to macroscopic critical-state models. At each stage it is found that a key nondimensional parameter is Λ = λ2/dL...
متن کاملO ct 1 99 9 Transitions between different superconducting states in mesoscopic disks
Using a linear analysis, we study the stability of giant–vortex states in very thin disks. The vortex expulsion and penetration fields are obtained for finite thickness disks from a numerical solution of the non-linear Ginzburg–Landau (GL) equations. Using an extension of the London approximation, in which the phase distribution of the order parameter is prescribed and the superconducting elect...
متن کاملMesoscopic rings : two - fluid model
Kinetics of magnetic flux in the thin mesoscopic ring biased by an external magnetic flux exhibits the ratchet-like behavior. The 'flux velocity', i.e. the averaged time derivative of magnetic flux produced by the ring, is a candidate for a novel characteristics of mesoscopic rings. Its global properties reflect the possibility of accommodating persistent currents in the ring. 1 Mesoscopic ring...
متن کاملDirect Measurement of Penetration Length in Ultra-Thin and/or Mesoscopic Superconducting Structures
As the dimensions of thin superconducting structures become comparable with or less than the penetration length of magnetic flux into the structures, it becomes increasingly necessary to devise experimental tests of available theoretical models. One approach which we shall describe, enables penetration lengths to be derived from the measurement of the effective area of planar, thin-film structu...
