  Non-resonant circularly polarized electromagnetic radiation can exert torques
on magnetization by the Inverse Faraday Effect (IFE). Here we discuss the
enhancement of IFE by spin-orbit interactions (SOI). We illustrate the
principle by studying a simple generic model system, i.e. the quasi-1D ring in
the presence of linear/cubic Rashba and Dresselhaus interactions. We combine
the classical IFE in electron plasmas that is known to cause persistent
currents in the plane perpendicular to the direction of the propagation of
light with the concept of current and spin-orbit-induced spin transfer torques.
We calculate light-induced spin polarization that in ferromagnets might give
rise to magnetization switching.
