Very recently, the half-metallic compound Co3Sn2S2 was proposed to be a magnetic Weyl semimetal (WSM) with Weyl points only 60 meV above the Fermi level E-F. Owing to the low charge carrier density and large Berry curvature induced, Co3Sn2S2 possesses both a large anomalous Hall conductivity and a large anomalous Hall angle, which provide strong evidence for the existence of Weyl points in Co3Sn2S2. In this work, we theoretically study the surface topological feature of Co3Sn2S2 and its…

The investigation of magneto-transport measurements in single crystals of magnetic Weyl semimetal Co3Sn2S2 shows a turn-on like behaviour followed by saturation in resistivity under magnetic field in the low temperature region which allocates to the topological surface states, and evidence for time reversal symmetry breaking is provided.
