Query: Flux flow spin Hall effect in type-II superconductors with
  spin-splitting field   We predict the very large spin Hall effect in type-II superconductors which
mechanism is drastically different from the previously known ones. We find that
in the flux-flow regime the spin is transported by the spin-polarized Abrikosov
vortices moving under the action of the Lorenz force in the direction
perpendicular to the applied electric current. Due to the large vortex
velocities the spin Hall angle can be of the order of unity in realistic
systems based on the high-field superconductors or the recently developed
superconductor/ferromagnetic insulator proximity structures. We propose the
realization of high-frequency pure spin current generator based on the periodic
structure of moving vortex lattices. We find the patterns of charge imbalance
and spin accumulation generated by moving vortices, which can be used for the
electrical detection of individual vortex motion. The new mechanism of inverse
flux-flow spin Hall effect is found based on the driving force acting on the
vortices in the presence of injected spin current which results in the
generation of transverse voltage.
