Field-dependent Shubnikov-de Haas oscillations in ferromagnetic Weyl semimetal Co3Sn2S2
Linda Ye, Jorge I. Facio, Madhav P. Ghimire +6
We report a study of Shubnikov-de Haas oscillations in high quality single crystals of ferromagnetic Weyl semimetal CoSnS. The Fermi surfaces resolved in our experiment…
Ferromagnetic helical nodal line and Kane-Mele spin-orbit coupling in kagome metal Fe3Sn2
Shiang Fang, Linda Ye, Madhav Prasad Ghimire +8
The two-dimensional kagome lattice hosts Dirac fermions at its Brillouin zone corners K and K', analogous to the honeycomb lattice. In the density functional theory electronic stru…
Tunable chirality of noncentrosymmetric magnetic Weyl semimetals
Rajyavardhan Ray, Banasree Sadhukhan, Manuel Richter +2
Even if Weyl semimetals are characterized by quasiparticles with well-defined chirality, exploiting this experimentally is severely hampered by Weyl lattice-fermions coming in pair…
Potassium-intercalated bulk HfS and HfSe: Phase stability, structure, and electronic structure
Carsten Habenicht, Jochen Simon, Manuel Richter +3
We have studied potassium-intercalated bulk HfS and HfSe by combining transmission electron energy loss spectroscopy, angle-resolved photoemission spectroscopy and density…
Strong and Weak Three-Dimensional Topological Insulators Probed by Surface Science Methods
Markus Morgenstern, Christian Pauly, Jens Kellner +12
We review the contributions of surface science methods to discover and improve 3D topological insulator materials, while illustrating with examples from our own work. In particular…
Large off diagonal exchange couplings and spin liquid states in symmetric iridates
Ravi Yadav, Satoshi Nishimoto, Manuel Richter +2
Iridate oxides on a honeycomb lattice are considered promising candidates for realization of quantum spin liquid states. We investigate the magnetic couplings in a structural model…
