Fermi-arc diversity on surface terminations of the magnetic Weyl semimetal Co 3 Sn 2 S 2

Magnetic Weyl semimetals Weyl semimetals (WSMs)—materials that host exotic quasiparticles called Weyl fermions—must break either spatial inversion or time-reversal symmetry. A number of WSMs that break inversion symmetry have been identified, but showing unambiguously that a material is a time-rever... View More
