Nematicity in LaFeAsO single crystals studied by elastoresistance, high-resolution thermal expansion and shear-modulus measurements
X. C. Hong, S. Sauerland, L. Wang +10
Nematicity in LaFeAsO single crystals is studied by means of high-resolution thermal expansion, shear modulus, and elastoresistivity measurements. A softening of the shear modulus…
Point-contact enhanced superconductivity in trigonal PtBi2: quest for the origin of high-Tc
O. E. Kvitnitskaya, L. Harnagea, G. Shipunov +6
We studied enhanced superconductivity in point contacts (PCs) based on a type-I Weyl semimetal trigonal t-PtBi2 using both normal metal (Ag, Cu, Pt) and ferromagnetic (Fe, Co, Ni)…
Microscopic NMR evidence for successive antiferroelectric and antiferromagnetic order in the van der Waals magnet CuCrPS
C. S. Saramgi, L. F. Prager, S. Selter +5
We present a comprehensive P and Cu nuclear magnetic resonance (NMR) study of the layered van der Waals magnet CuCrPS. The compound exhibits a sequence of str…
Magnetic-field tuning of the spin dynamics in the quasi-2D van der Waals antiferromagnet CuCrPS
Joyal John Abraham, Yaqian Guo, Yuliia Shemerliuk +14
The use of antiferromagnets in magnetoelectronic devices as counterparts of ferromagnets is a new, rapidly developing trend in spintronics that leverages antiferromagnetic (AFM) ma…
Hysteretic Phonons and Quasielastic Response: A Raman Study of Thermal Memory in Two-dimensional CuCrP2S6
Chaitanya B. Auti, Atul G. Chakkar, Sebastian Selter +4
We present a comprehensive temperature and polarization dependent inelastic light scattering (Raman) study on single crystals of two-dimensional CuCrP2S6, a layered van der Waals m…
Magneto-elasto-resistivity in FeSe
M. Wissmann, L. Fanfarillo, X. -C. Hong +6
FeSe stands out among iron-based superconductors due to its extended nematic phase without the onset of long-range magnetic order. While strain-dependent electrical resistivity has…
