Superconductivity with Tc=7 K under pressure for Cu-, and Au-doped BaFe2As2
L. Li, D. S. Parker, Z. Gai +2
It is noteworthy that chemical substitution of BaFe2As2 (122) with the noble elements Cu and Au gives superconductivity with a maximum Tc=3 K, while Ag substitution (Ag-122) stays…
Competitive and Cooperative electronic states in Ba(FeT)As with T=Co, Ni, Cr
Qiang Zou, Mingming Fu, Zhiming Wu +4
The electronic structure inhomogeneities in Co, Ni, and Cr doped BaFe2As2 122 single crystals are compared using scanning tunneling microscopy/spectroscopy (STM/S) at the nanoscale…
Nanoscale Interlayer Defects in Iron Arsenides
Qiang Zheng, Miaofang Chi, Maxim Ziatdinov +5
Using a local real-space microscopy probe, we discover evidence of nanoscale interlayer defects along the c-crystallographic direction in BaFe2As2 (122) based iron-arsenide superco…
Lattice Disorder Effect on Magnetic Ordering of Iron Arsenides
Athena S. Sefat, Xiaoping P. Wang, Yaohua Liu +7
This study investigates the changes of magnetic ordering temperature via nano- and mesoscale structural features in an iron arsenide. Although magnetic ground states in quantum mat…
On the origin of critical nematic fluctuations in pnictide superconductors
S. -F. Wu, W. -L. Zhang, L. Li +6
We employ polarization-resolved Raman spectroscopy to study critical nematic fluctuations in Ba(FeAu)As superconductors above and across well separated tetragon…
Effect of surface morphology and magnetic impurities on the electronic structure in cobalt-doped BaFe2As2 superconductors
Qiang Zou, Zhiming Wu, Mingming Fu +8
Combined scanning tunneling microscopy, spectroscopy and local barrier height (LBH) studies show that low-temperature-cleaved optimally-doped Ba(Fe1-xCox)2As2 crystals with x=0.06,…
