Filamentary superconductivity across the phase diagram of Ba(Fe,Co)As
H. Xiao, T. Hu, S. K. He +10
We show magnetotransport results on Ba(FeCo)As () single crystals. We identify the low temperature resistance step at 23 K in the parent c…
From d-wave to s-wave pairing in the iron-pnictide superconductor (Ba,K)Fe2As2
J. -Ph. Reid, A. Juneau-Fecteau, R. T. Gordon +18
The nature of the pairing state in iron-based superconductors is the subject of much debate. Here we argue that in one material, the stoichiometric iron pnictide KFe2As2, there is…
BaFe2Se2O as an Iron-Based Mott Insulator with Antiferromagnetic Order
Fei Han, Xiangang Wan, Bing Shen +1
A new compound with a quasi-two-dimensional array of FeSe3O tetrahedra and an orthorombic structure, namely BaFe2Se2O, has been successfully fabricated. Experimental results show t…
Vortex creep and critical current densities in superconducting (Ba,K)FeAs single crystals
Marcin Konczykowski, Cornelis Jacominus van der Beek, Makariy Tanatar +5
The surprisingly rapid relaxation of the sustainable current density in the critical state of single crystalline BaKFeAs is investigated for magnetic fiel…
Metastable superconducting state in quenched KxFe2-ySe2
Fei Han, Huan Yang, Bing Shen +3
By direct quenching or post-annealing followed by quenching, we have successfully obtained a series of KxFe2-ySe2 samples with different properties. It is found that the samples di…
Evidence of a spin resonance mode in the iron-based superconductor BaKFeAs from scanning tunneling spectroscopy
Lei Shan, Jing Gong, Yong-Lei Wang +8
We used high-resolution scanning tunneling spectroscopy to study the hole-doped iron pnictide superconductor BaKFeAs ( K). Features of a bosonic…
