Nb 2 Cl 10 ( P 4 S 10 ) 2 : A Co - Crystal of Nb 2 Cl 10 and P 4 S 10 Arno Pfitzner * and Diana

Red moisture sensitive crystals of Nb2Cl10(P4S10)2 were obtained from a solution of P4S10 and Nb2Cl10 in CS2. Nb2Cl10(P4S10)2 crystallises in the space group P1̄ with a 9.577(2), b 10.894(2), c 11.477(2) Å, 71.40(1), β 68.14(1), γ 67.58(1)°; V 1005.2(3) Å3, Z 2. In the crystal structure molecules of P4S10 and Nb2Cl10 are arranged similar to the packing of the ions in the CaF2 structure type. A c...

A STUDY OF Nb 3 (

A STUDY OF Nb 3 (A1.75Ge.2 5 ) AND V3 Au SUPERCONDUCTING TUNNEL JUNCTIONS by JAMES ALLEN GREGORY Nb3(Al 75Ge2 5 ) Pb7Bi3 and V3Au-In superconducing tunnel junctions have been fabricated. Various methods of surface preparation, oxidation, and junction fabrication have been investigated. The tunneling data obtained from the Nb3(A17 5Ge2 5 ) junctions indicate a superconducting energy gap, 2A, of ...

Self-shunted Nb/AlOx/Nb Josephson junctions

We describe the fabrication and properties of high critical current density (Jc) Nb/AlOx/Nb Josephson junctions with deep-submicron dimensions. The junctions are fabricated using a planarized process in which all levels are patterned using a combination of optical and electron beam lithography. The base and counter electrodes are defined by reactive ion etching using quartz etch masks to give a...

Transport properties of Nb/PdNi bilayers and Nb/PdNi/Nb Josephson junctions

The superconducting proximity effect was examined in both Nb/PdNi (SF) bilayer films and Nb/PdNi/Nb (SFS) Josephson junctions. In Nb/PdNi bilayer films, nonmonotonic behavior of Tc was observed as a function of PdNi thickness dF. The effective exchange energy Eex extracted from the data was about 13 meV. In Nb/PdNi/Nb (SFS) Josephson junctions, the existence of a crossover between the 0 state a...
