Pressure-induced superconductivity and topological quantum phase transitions in a quasi-one-dimensional topological insulator: Bi4I4
Yanpeng Qi, Wujun Shi, Peter Werner +8
Superconductivity and topological quantum states are two frontier fields of research in modern condensed matter physics. The realization of superconductivity in topological materia…
Unusual magneto-transport from Si-square nets in topological semimetal HfSiS
Nitesh Kumar, Kaustuv Manna, Yanpeng Qi +5
The class of topological semimetals comprises a large pool of compounds. Together they provide a wide platform to realize exotic quasiparticles for example Dirac, nodal line Dirac…
Calculation of the transport critical current density of c-axis textured 122 iron-based superconductors
Lei Wang, Jinghui Xu, Duoduo Ba +4
The c-axis textured Sr1-xKxFe2As2 tapes produced by cold rolling and post-annealing, could carry a high super-current over 2*104 A/cm2. However, the magnitude is far from its maxim…
Improved transport critical currents in Ag and Pb co-doped BaxK1-xFe2As2 superconducting tapes
Chao Yao, Chunlei Wang, Xianping Zhang +8
Fe-clad BaxK1-xFe2As2 superconducting tapes were fabricated by the ex situ powder-in-tube method combined with a short high-temperature annealing technique. The effect of annealing…
High transport critical current densities in textured Fe-sheathed Sr1-xKxFe2As2+Sn superconducting tapes
Zhaoshun Gao, Lei Wang, Chao Yao +6
We report the realization of grain alignment in Sn-added Sr1-xKxFe2As2 superconducting tapes prepared by ex-situ powder-in-tube method. At 4.2 K, high transport critical current de…
Transport properties and anisotropy in rare earth doped CaFe2As2 single crystals with Tc above 40 K
Yanpeng Qi, Zhaoshun Gao, Lei Wang +6
In this paper we report the superconductivity above 40 K in the electron doping single crystal Ca1-xRexFe2As2 (Re = La, Ce, Pr). The x-ray diffraction patterns indicate high crysta…
