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}…
Ultra-high critical current densities, the vortex phase diagram and the effect of granularity of the stoichiometric high-Tc superconductor, CaKFeAs
Shiv J. Singh, Matthew Bristow, William Meier +4
We present a comprehensive study of the critical current densities and the superconducting vortex phase diagram in the stoichiometric superconductor CaKFeAs which has a cri…
Measurements of the lower critical field of superconductors using NV centers in diamond optical magnetometry
K. R. Joshi, N. M. Nusran, K. Cho +5
The lower critical magnetic field, , of superconductors is measured by using ensembles of NV-centers-in-diamond optical magnetometry. The technique is minimally invasive, a…
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…
Subdominant -wave interaction in superconducting CaKFeAs?
Daniel Jost, Jan-Robin Scholz, Ulrike Zweck +5
We report inelastic light scattering results on the stoichiometric and fully ordered superconductor CaKFeAs as a function of temperature and light polarization. In the ener…
