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…
Quantum tricritical point in the temperature-pressure-magnetic field phase diagram of CeTiGe
Udhara S. Kaluarachchi, Valentin Taufour, Sergey L. Bud'ko +1
We report the temperature-pressure-magnetic field phase diagram of the ferromagnetic Kondo-lattice CeTiGe determined by means of electrical resistivity measurements. Measuremen…
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…
Direct visualization of phase separation between superconducting and nematic domains in Co-doped CaFe2As2 close to a first order phase transition
Antón Fente, Alexandre Correa-Orellana, Anna E. Böhmer +9
We show that biaxial strain induces alternating tetragonal superconducting and orthorhombic nematic domains in Co substituted CaFe2As2. We use Atomic Force, Magnetic Force and Scan…
Dynamic Elastoresistivity Evidence for Slow Nematic Fluctuations in BaFeAs
Gil Drachuck, Michael Schütt, Anna E. Böhmer +6
An instrumentation problem with the signal acquisition at high frequencies was discovered and we no longer believe that the experimental data presented in the manuscript, showing a…
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…
