Se p 20 04 Vortex - glass transition in superconducting Nb / Cu superlattices
نویسندگان
چکیده
Nb/Cu superconducting superlattices have been fabricated by dc magnetron sputtering. This system shows a vortex glass transition with critical exponents similar to high temperatures super-conductors exponents. The transition dymensionality is governed by the superconducting coupling regime. The vortex glass transition shows a pure two dimensional behavior in decoupled superlat-tices and a quasi-two dimensional behavior in the superlattice coupling regime.

Transition Temperatures and Critical Fields of Nb/Cu Superlattices
We present experimental results on the superconducting properties of Nb / Cu superlattices. The transition temperature of the superlattice implies a decrease in the transition temperature of single Nb films as a function of layer thickness. This is interpreted as due to the mean free path-induced decrease in the density of states at the Fermi surface, in agreement with experimentally measured m...
متن کاملEnhancement of superconductivity by decreased magnetic spin-flip scattering: Nonmonotonic TC dependence with enhanced magnetic ordering
Fe/Cu superlattices exhibit a structural and magnetic transition with increasing Fe layer thickness, thus increasing the Curie temperature. An enhancement in the superconducting transition temperature is found in proximity coupled Nb/@Fe/Cu# layers as the Fe thickness increases. These results indicate a weakening of the magnetic proximity effect for the material with higher Curie temperature, a...
متن کاملDirect demonstration of circulating currents in a controllable p-SQUID generated by a 0 to p transition of the weak links
A controllable p-SQUID is a DC SQUID ~direct-current superconducting quantum interference device! with two controllable p junctions as weak links. A controllable p junction consists of a superconducting–normal metal–superconducting Josephson junction with two additional contacts to the normal region of the junction. By applying a voltage Vc over these contacts it is possible to control the stat...
متن کاملParamagnetic Reentrance Effect in NS Proximity Cylinders
A scenario for the unusual paramagnetic reentrance behavior at ultra-low temperatures in Nb-Ag, Nb-Au, and Nb-Cu cylinders is presented. For the diamagnetic response down to temperatures of the order 15 mK, the standard theory (quasi-classical approximation) for superconductors appears to work very well, assuming that Ag, Au, and Cu remain in the normal state except for the proximity-induced su...
متن کاملQuantum Turbulence Generated by Grid Motion in Superfluid He
The mechanism by which the quantized vortex tangle in a turbulent superfluid system decays remains little understood [1]. Research into the subject suggests that Kelvin waves play an integral part in the dissipation process [2]. To generate quantum turbulence, a grid is dragged through 4 He which has condensed into the superfluid state. Oscillations in the motion of this grid remain a problem, ...
