Tunable optical injection of chiral-polarized Weyl fermions. (IMAGE)
Caption
(a) Schematic illustration of the tunable injection of chiral polarized Weyl fermions. In the presence of an electric field, the chirality of circularly polarized light can couple with the chirality of magnetic Weyl cones, resulting in the injection of chiral polarized Weyl fermions, which manifests as the generation of IA .The injection of chiral polarized Weyl fermions can be flexibly controlled by the FM order or the external electric field. (b) Distribution of IA measured under opposite magnetization and electric field directions. All scale bars are 10 μm.
