Coexistence of Type‑I and Type-II Weyl Points in the Weyl-Semimetal OsC₂

The topologically nontrivial Weyl semimetals have two different types: (i) the standard Weyl cones with point-like Fermi surfaces (type-I) and (ii) tilted Weyl cones that appear at the contact of electron and hole pockets (type-II). These two types of Weyl semimetals have significantly different physical properties in their thermodynamics and magnetotransport. Here we presented a compound OsC₂ with both types Weyl points (WPs) at the equilibrium volume. It has 24 type-I WPs in the <i>K</i>_<i>z</i> = ±0.0241 ×2πc planes around <i>K</i> (or <i>K</i>′) points and 12 type-II WPs in the <i>K</i>_<i>z</i> = ±0.4354 ×2πc planes at the projected <i>K</i> (<i>K</i>′) point, respectively. The type-I WPs are connected by the helix-trimer Fermi arcs
