Inversion symmetry breaking is critical for many quantum effects and fundamental for spin‐orbit torque, which is crucial for next‐generation spintronics. Recently, a novel type of gigantic intrinsic spin‐orbit torque is established in the topological van der Waals (vdW) magnet iron germanium telluri...
