Scattering of ferromagnetic band-electrons by phonons combined with the spin–orbit interaction is shown to cause magnetic relaxation of the Landau–Lifshitz–Gilbert type. Two formally distinct processes are simply analyzed: (a) spin-flip scattering of electrons and (b) ordinary scattering between spin-dependent band levels. Estimates of the magnitude of the damping constant λ are derived for both cases, which agree in orders of magnitude with the experimental values for Fe and Ni. Relations of direct and inverse proportionality between λ and the ordinary collision frequency are found in the cases (a) and (b), respectively.

AbstractVan der Waals heterostructures composed of multiple few layer crystals allow the engineering of novel materials with predefined properties. As an example, coupling graphene weakly to materials with large spin–orbit coupling (SOC) allows to engineer a sizeable SOC in graphene via proximity effects. The strength of the proximity effect depends on the overlap of the atomic orbitals, therefore, changing the interlayer distance via hydrostatic pressure can be utilized to enhance the interlayer coupling between the layers. In this work, we report measurements on a graphene/WSe2 heterostructure exposed to increasing hydrostatic pressure. A clear transition from weak localization to weak antilocalization is visible as the pressure increases, demonstrating the increase of induced SOC in graphene.
