Quantum oscillation and unusual protection mechanism of the surface state in nonsymmorphic semimetals
Xue Liu, Chunlei Yue, Sergey V. Erohin +9
In a topological semimetal with Dirac or Weyl points, the bulk edge correspondence principle predicts a gapless edge mode if the essential symmetry is still preserved at the surfac…
Transition from Intrinsic to Extrinsic Anomalous Hall Effect in the Ferromagnetic Weyl Semimetal PrAlGeSi
Hung-Yu Yang, Bahadur Singh, Baozhu Lu +10
Recent reports of a large anomalous Hall effect (AHE) in ferromagnetic Weyl semimetals (FM WSM) have led to a resurgence of interest in this enigmatic phenomenon. However, due to a…
Transport evidence of triply degenerate nodal semimetal YRh6Ge4
Yanglin Zhu, Xin Gui, Yu Wang +3
We have investigated magnetotransport properties of YRh6Ge4, which was recently predicted to be a triply degenerate nodal semimetal. We find it exhibits remarkable signatures of a…
Electrical and magnetic properties of thin films of the spin-filter material CrVTiAl
Gregory M. Stephen, Christopher Lane, Gianina Buda +5
The spin-filter material CrVTiAl is a promising candidate for producing highly spin-polarized currents at room temperature in a nonmagnetic architecture. Thin films of compensated-…
Dirac fermions and flat bands in the ideal kagome metal FeSn
Mingu Kang, Linda Ye, Shiang Fang +19
The kagome lattice based on 3d transition metals is a versatile platform for novel topological phases hosting symmetry-protected electronic excitations and exotic magnetic ground s…
Switching 2D Magnetic States via Pressure Tuning of Layer Stacking
Tiancheng Song, Zaiyao Fei, Matthew Yankowitz +15
The physical properties of two-dimensional van der Waals (2D vdW) crystals depend sensitively on the interlayer coupling, which is intimately connected to the stacking arrangement…
