Popis: Weyl semimetals exhibit a unique feature known as Weyl nodes, which give rise to non-trivial topological features such as an anomalous Hall effect, and there are many efforts to try and control such properties. Here, the authors report light-induced chirality switching in a ferromagnetic Weyl semimetal Co3Sn2S2 using circularly polarized mid-infrared light pulse excitation.
