A new road towards spin-polarized currents

"new route towards generation of spin-polarized currents from transition metal dichalcogenides... some select materials such as HfSe2... If you probe this material with linearly-polarized light—which is easier to produce than circularly polarized light—the material acts as a magnet in terms of its spin-structure. So the spin-selectivity becomes very easy, but you do not have the problems associated with other magnetic properties"
