Nearly-critical spin and charge fluctuations in KFe2As2 observed by high-pressure NMR
P. S. Wang, P. Zhou, J. Dai +7
We report a high-pressure 75As NMR study on the heavily hole-doped iron pnictide superconductor KFe2As2 (Tc~3.8 K). The low-energy spin fluctuations are found to decrease with appl…
Observation of a van Hove singularity and implication for strong coupling induced Cooper pairing in KFe2As2
Delong Fang, Xun Shi, Zengyi Du +14
Scanning tunneling spectroscopy (STS) and angle-resolved photoemission spectroscopy (ARPES) have been investigated on single crystal samples of KFe2As2. A van Hove singularity (vHs…
Strong and nonmonotonic temperature dependence of Hall coefficient in superconducting KFeSe single crystals
Xiaxin Ding, Yiming Pan, Huan Yang +1
In-plane resistivity, magnetoresistance and Hall effect measurements have been conducted on quenched KFeSe single crystals in order to analysis the normal-state tra…
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…
