Coexistence of superconductivity and magnetism in CaK(FeNi)As as probed by Fe Mössbauer spectroscopy
Sergey L. Bud'ko, Vladimir G. Kogan, Ruslan Prozorov +3
Temperature dependent Fe Mössbauer spectroscopy and specific heat measurements for CaK(FeNi)As with = 0, 0.017, 0.033, and 0.049 are presented. No ma…
Hedgehog Spin-vortex Crystal Antiferromagnetic Quantum Criticality in CaK(Fe1-xNix)4As4 Revealed by NMR
Q. -P. Ding, W. R. Meier, J. Cui +5
Two ordering states, antiferromagnetism and nematicity, have been observed in most iron-based superconductors (SCs). In contrast to those SCs, the newly discovered SC CaK(Fe$_{1-x}…
Antiferromagnetic order in CaK(Fe[1-x]Ni[x])4As4 and its interplay with superconductivity
A. Kreyssig, J. M. Wilde, A. E. Böhmer +9
The magnetic order in CaK(Fe[1-x]Ni[x])4As4 (1144) single crystals (x = 0.051 and 0.033) has been studied by neutron diffraction. We observe magnetic Bragg peaks associated to the…
Pressure-temperature phase diagrams of CaK(FeNi)As superconductors
Li Xiang, William R. Meier, Mingyu Xu +3
The pressure dependence of the magnetic and superconducting transitions, as well as that of the superconducting upper critical field is reported for CaK(FeNi)As$_…
Robust s+/- pairing in CaK[Fe(1-x)Ni(x)]4As4$ (x = 0 and 0.05) from the response to electron irradiation
S. Teknowijoyo, K. Cho, M. Konczykowski +7
Controlled point-like disorder introduced by 2.5 MeV electron irradiation was used to probe the superconducting state of single crystals of \CaKx\ superconductor at and 0.0…
