Weyl Metal Phase in Delafossite Oxide PtNiO
Gang Bahadur Acharya, Mohan Bikram Neupane, Rojila Ghimire +1
On the basis of density functional theory calculations we predict Weyl points in rhombohedral structure of PtNiO having symmorphic symmetry. From the formation energy and phono…
CoTe2: A quantum critical Dirac metal with strong spin fluctuations
Peter E. Siegfried, Hari Bhandari, Jeanie Qi +13
Quantum critical points separating weak ferromagnetic and paramagnetic phases trigger many novel phenomena. Dynamical spin fluctuations not only suppress the long-range order, but…
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…
Origin of spin reorientation and intrinsic anomalous Hall effect in the kagome ferrimagnet TbMn6Sn6
D. Connor Jones, Suvadip Das, Hari Bhandari +6
TbMnSn has attracted a lot of recent interest for a variety of reasons, most importantly, because of the hypothesis that it may support quantum-limit Chern topological magn…
Plethora of tunable Weyl fermions in kagome magnet Fe3Sn2 thin films
Zheng Ren, Hong Li, Shrinkhala Sharma +9
Interplay of magnetism and electronic band topology in unconventional magnets enables the creation and fine control of novel electronic phenomena. In this work, we use scanning tun…
