Uniaxial strain tuned magnetism of the altermagnet candidate h-FeS
Weiliang Yao, Feng Ye, Zachary J. Morgan +9
Altermagnets are collinear magnetic materials with 'alter'nating local crystalline environments, characterized by joint spin and crystalline symmetries that enable ferromagnetic-li…
Atomically-sharp magnetic soliton in the square-net lattice EuRhAlSi
Kevin Allen, Juba Bouaziz, Yichen Zhang +17
Topological spin textures are hallmark manifestations of competing interactions in magnetic matter. Their effective description by nonlinear field theories reflects an energetic fr…
Quantum oscillations and anisotropic magnetoresistance in the quasi-two-dimensional Dirac nodal line superconductor
Yuxiang Gao, Kevin Allen, Rose Albu Mustaf +8
Recent interest in quantum materials has focused on systems exhibiting both superconductivity and non-trivial band topology as material candidates to realize topological or unconve…
Fermi surface and Berry phase analysis for Dirac nodal line semimetals: cautionary tale to SrGa and BaGa
Yuxiang Gao, Yichen Zhang, Shiming Lei +8
A Berry phase of odd multiples of inferred from quantum oscillations (QOs) has often been treated as evidence for nontrivial reciprocal space topology. However, disentangling…
Kramers nodal lines in intercalated TaS superconductors
Yichen Zhang, Yuxiang Gao, Aki Pulkkinen +24
Kramers degeneracy is one fundamental embodiment of the quantum mechanical nature of particles with half-integer spin under time reversal symmetry. Under the chiral and noncentrosy…
Anomalous Electrical Transport in the Kagome Magnet YbFeGe
Weiliang Yao, Supeng Liu, Hodaka Kikuchi +19
Two-dimensional (2D) kagome metals offer a unique platform for exploring electron correlation phenomena derived from quantum many-body effects. Here, we report a combined study of…
