Femtosecond spin-to-charge current conversion in FeCo/graphene nanobilayer excited by femtosecond optical laser pulse

The generation of THz transients in a FeCo/graphene nanobilayer, excited by femtosecond optical laser pulses is demonstrated. We assign the mechanism of the THz radiation to the inverse Rashba-Edelstein effect in graphene with λ
