TLDR
In this paper, it was shown that spin polarization can also be achieved without the need for magnetism by using the unique crystal symmetry of tungsten selenide, which creates a Zeeman-like effect when a monolayer of the material is exposed to an external electric field.Abstract:
A magnetic field can lift the spin degeneracy of electrons. This Zeeman effect is an important route to generating the spin polarization required for spintronics. It is now shown that such polarization can also be achieved without the need for magnetism. The unique crystal symmetry of tungsten selenide creates a Zeeman-like effect when a monolayer of the material is exposed to an external electric field.read more

Symmetry, spin-texture, and tunable quantum geometry in a WTe 2 monolayer
TL;DR: In this paper, it was shown that a gate-activated canted spin texture produces an electrically tunable bulk band quantum geometry, and that due to its out-of-plane asymmetry, an applied out of-plane electric field breaks inversion symmetry to induce both in-plane and outofplane electric dipoles, which in turn generate spin-orbit coupling and enable a bulk band Berry curvature and magnetic moment distribution.
