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…
Full Electroresistance Modulation in a Mixed-Phase Metallic Alloy
Z. Q. Liu, L. Li, Z. Gai +11
We report a giant, ~22%, electroresistance modulation for a metallic alloy above room temperature. It is achieved by a small electric field of 2 kV/cm via piezoelectric strain-medi…
