WebJul 5, 2024 · Furthermore, by considering spin–orbit coupling, spin and valley degeneracy splitting are achieved simultaneously in Hg-substituted MnPSe 3. A data storage device prototype is proposed for future applications based on the anomalous valley Hall effects in this ferrovalley material. WebAb initio calculations show that this thickness independent splitting pattern is a direct consequence of the giant spin-valley coupling which fully suppresses interlayer hopping at valence band edge near K points because of the sign change of the spin-valley coupling from layer to layer in the 2H stacking order. texliving
