Query: Optically induced spin-dependent diffusive transport in the presence of
  spin-orbit interaction for all-optical magnetization reversal   We have considered the effect of different spin-orbit interaction mechanisms
on the process of demagnetization under the influence of short-pulse lasers.
All-optical magnetization reversal of perpendicularly magnetized thin films can
occur if there are sufficient strong spin-Hall, skew scattering, and Rashba
interactions. In the presence of spin-orbit interactions, the transient charge
currents provide the generation of transverse-spin currents and accumulations,
which eventually exert spin-transfer torque on the magnetization. By combining
the optically excited spin-dependent diffusive transport with the spin and
charge currents due to skew scattering, spin-Hall, inverse spin-Hall and Rashba
interactions, into a numerical model, we demonstrate a possibility of
ultra-fast all-optical magnetization reversal. This understanding provokes
intriguing, more in-depth experimental studies on the role of spin-orbit
interaction mechanisms in optimizing structures for all-optical magnetization
reversal.
