The spin orientation of electronic wave functions in crystals is an internal degree of freedom, typically insensitive to electrical knobs. We argue from a general symmetry analysis and a k⋅p perspective, that monolayer 1T′−WTe2 possesses a gate-activated canted spin texture that produces an electric...
