The Josephson current in Fe-based superconducting junctions: theory and experiment
A. V. Burmistrova, I. A. Devyatov, A. A. Golubov +8
We present theory of dc Josephson effect in contacts between Fe-based and spin-singlet -wave superconductors. The method is based on the calculation of temperature Green's funct…
Impurity effect and suppression to superconductivity in Na(FeCoT)As (T=Cu, Mn)
Qiang Deng, Xiaxin Ding, Sheng Li +3
We report the successful growth and the impurity scattering effect of single crystals of Na(FeCoT)As (T=Cu, Mn). The temperature dependence of DC magnetizat…
Orbital-Selective Mottness in KxFe2-ySe2 Superconductors Revealed by Pump-Probe Spectroscopy
Wei Li, Chunfeng Zhang, Shenghua Liu +5
We report transient optical signatures of the orbital-selective Mottness in superconducting KxFe2-ySe2 crystals by using dual-color pump-probe spectroscopy. Besides multi-exponenti…
Strong coupling superconductivity and prominent superconducting fluctuations in the new superconductor Bi4O4S3
Sheng Li, Huan Yang, Delong Fang +4
Electric transport and scanning tunneling spectrum (STS) have been investigated on polycrystalline samples of the new superconductor Bi4O4S3. A weak insulating behavior in the resi…
Influence of microstructure on superconductivity in KFeSe and evidence for a new parent phase KFeSe
Xiaxin Ding, Delong Fang, Zhenyu Wang +7
The search for new superconducting materials has been spurred on by the discovery of iron-based superconductors whose structure and composition is qualitatively different from the…
