Dynamics of femtosecond magnetization reversal induced by circularly polarized light in the presence of fluctuations and dissipation
A. Rebei, J. Hohlfeld
Magnetization reversal by a femtosecond circularly polarized laser pulse has been recently demonstrated in rare-earth doped transition metals (RE-TM). The switching mechanism has b…

The magneto-optical Barnett effect and spin momentum transfer:Magnetization switching by circularly polarized light
A. Rebei, J. Hohlfeld
The interaction of polarized light with a spin in the presence of dissipation is shown to be equivalent to a spin transfer process that can cause switching. In plasmas, the spin tr…
