Tunable Anomalous Hall Effect in a Kagome Ferromagnetic Weyl Semimetal.

ABSTRACT: Emerging from the intricate interplay of topology and magnetism, the giant anomalous Hall effect (AHE) is the most known topological property of the recently discovered kagomé ferromagnetic Weyl semimetal Co₃Sn₂S₂ with the magnetic Co atoms arranged on a kagomé lattice. Here it is reported that the AHE in Co₃Sn₂S₂ can be fine-tuned by an applied magnetic field orientated within ≈2° of the kagomé plane, while beyond this regime, it stays unchanged. Particularly, it can vanish in magnetic fields parallel to the kagomé plane and even decrease in magnetic fields collinear with the spin direction. This tunable AHE can be attributed to local spin switching enabled by the geometrical frustration of the magnetic kagomé lattice, reve
