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…
Ultrasound evidence for multicomponent superconducting order parameter in BaKFeAs with electron quadrupling phase
Chris Halcrow, Ilya Shipulin, Federico Caglieris +6
Experiments have pointed to the formation of the electron quadrupling condensate in BaKFeAs at . The state spontaneously breaks time-reversal symmet…
Room temperature Planar Hall effect in nanostructures of trigonal-PtBi2
Arthur Veyrat, Klaus Koepernik, Louis Veyrat +13
Trigonal-PtBi2 has recently garnered significant interest as it exhibits unique superconducting topological surface states due to electron pairing on Fermi arcs connecting bulk Wey…
Inhomogeneity-driven multiform Spontaneous Hall Effect in conventional and unconventional superconductors
Nadia Stegani, Ilaria Pallecchi, Nicola Manca +10
The spontaneous Hall effect (SHE), a finite voltage occurring transversal to the electrical current in zero-magnetic field, has been observed in both conventional and unconventiona…
Evidence of pseudogap and absence of spin magnetism in the time-reversal-symmetry-breaking state of BaKFeAs
Florian Bärtl, Nadia Stegani, Federico Caglieris +13
Muon-spin-rotation (SR) experiments and the observation of a spontaneous Nernst effect indicate time-reversal symmetry breaking (BTRS) at above the superco…
Large Nernst effect in Te-based van der Waals materials
M. Behnami, M. Gillig, A. G. Moghaddam +14
Layered van der Waals tellurides reveal topologically non-trivial properties that give rise to unconventional magneto-transport phenomena. Additionally, their semimetallic characte…
