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

Phonon-derived ultrafast relaxation of spin-valley polarized states in MoS_{2}
TL;DR: In this paper, the spin precession of an electron in the valley is sharply coupled with the lowest-lying optical phonon that release the in-plane mirror symmetry, which indicates that spin randomization of MoS 2 is mainly caused by spin-phonon interaction.
