abstract = {We study laser-induced torques in bcc Fe, hcp Co, and L10
FePt based on first-principles electronic structure
calculations and the Keldysh nonequilibrium formalism. We
find that the torques have two contributions, one from the
inverse Faraday effect (IFE) and one from the optical
spin-transfer torque (OSTT). Depending on the ferromagnet at
hand and on the quasiparticle broadening the two
contributions may be of similar magnitude, or one
contribution may dominate over the other. Additionally, we
determine the nonequilibrium spin polarization in order to
investigate its relation to the torque. We find the torques
and the perpendicular component of the nonequilibrium spin
polarization to be odd in the helicity of the laser light,
while the spin polarization that is induced parallel to the
magnetization is helicity independent. The parallel
component of the nonequilibrium spin polarization is orders
of magnitude larger than the perpendicular component. In the
case of hcp Co we find good agreement between the calculated
laser-induced torque and a recent experiment.},
