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…
Theory of magnetic field-induced metaelectric critical end point in BiMnO
Gun Sang Jeon, Jin-Hong Park, Kee Hoon Kim +1
A recent experiment on the multiferroic BiMnO compound under a strong applied magnetic field revealed a rich phase diagram driven by the coupling of magnetic and charge (di…
Observation of a multiferroic critical end point
Jae Wook Kim, S. Y. Haam, Y. S. Oh +9
The study of abrupt increases in magnetization with magnetic field known as metamagnetic transitions has opened a rich vein of new physics in itinerant electron systems, including…
Enhanced Optical Gap in Bi-layered Manganites LaSrMnO near
Myung Whun Kim, H. J. Lee, B. J. Yang +4
We have systematically investigated the optical conductivity spectra of LaSrMnO (). We find that just above the magneti…
