NMR Study of the New Magnetic Superconductor CaK(Fe$0.951Ni0.049)4As4: Microscopic Coexistence of Hedgehog Spin-vortex Crystal and Superconductivity
Q. -P. Ding, W. R. Meier, A. E. Böhmer +3
Coexistence of a new-type antiferromagnetic (AFM) state, the so-called hedgehog spin-vortex crystal (SVC), and superconductivity (SC) is evidenced by As nuclear magnetic res…
NMR evidence for static local nematicity and its cooperative interplay with low-energy magnetic fluctuations in FeSe under pressure
P. Wiecki, M. Nandi, A. E. Böhmer +3
We present Se-NMR measurements on single-crystalline FeSe under pressures up to 2 GPa. Based on the observation of the splitting and broadening of the NMR spectrum due to st…
Growth and characterization of BaZnGa
Na Hyun Jo, Qisheng Lin, Manh Cuong Nguyen +12
We report the growth, structure and characterization of BaZnGa, identifying it as the sole known ternary compound in the Ba-Zn-Ga system. Single crystals of BaZnGa can be grown out…
Hedgehog spin-vortex crystal stabilized in a hole-doped iron-based superconductor
W. R. Meier, Q. -P. Ding, A. Kreyssig +12
Magnetism is widely considered to be a key ingredient of unconventional superconductivity. In contrast to cuprate high-temperature superconductors, antiferromagnetism in Fe-based s…
Magnetic fluctuations and superconducting properties of CaKFe4As4 studied by 75As NMR
J. Cui, Q. -P. Ding, W. R. Meier +8
We report As nuclear magnetic resonance (NMR) studies on a new iron-based superconductor CaKFeAs with = 35 K. As NMR spectra show two distinct lin…
Dome of magnetic order inside the nematic phase of sulfur-substituted FeSe under pressure
Li Xiang, Udhara S. Kaluarachchi, Anna E. Böhmer +5
The pressure dependence of the structural, magnetic and superconducting transitions and of the superconducting upper critical field were studied in sulfur-substituted Fe(Se…
