Josephson effect between electron-doped and hole-doped iron pnictide single crystals
Xiaohang Zhang, Shanta Saha, Nicholas P. Butch +8
We have observed the Josephson effect in junctions formed between single crystals of SrFe1.74Co0.26As2 and Ba0.23K0.77Fe2As2. I-V curves showed resistively-shunted junction charact…
Evidence for Coexistence of Superconductivity and Magnetism in Single Crystals of Co-doped SrFeAs
Jun Sung Kim, Seunghyun Khim, Liqin Yan +5
In order to investigate whether magnetism and superconductivity coexist in Co-doped SrFeAs, we have prepared single crystals of SrFeCoAs, = 0 and 0.4, a…
Observation of the Josephson effect in Pb/(Ba,K)Fe2As2 single crystal junctions
Xiaohang Zhang, Yoon Seok Oh, Yong Liu +4
We have fabricated c-axis Josephson junctions on single crystals of (Ba,K)Fe2As2 by using Pb as the counter electrode in two geometries, planar and point contact. Junctions in both…
Very high upper critical fields in MgB2 produced by selective tuning of impurity scattering
A. Gurevich, S. Patnaik, V. Braccini +16
We report a significant enhancement of the upper critical field of different samples alloyed with nonmagnetic impurities. By studying films and bulk polycrystals w…
