Magnetization dynamics induced by femtosecond light pulses

Work on magnetization dynamics induced by femtosecond light pulses is reviewed. It is shown that the effect of ultrashort light pulses on spins can be represented as the effect of an effective magnetic field. Thus, optically-induced magnetization dynamics can be described by the Landau-Lifshitz equa...

Description
Summary:Work on magnetization dynamics induced by femtosecond light pulses is reviewed. It is shown that the effect of ultrashort light pulses on spins can be represented as the effect of an effective magnetic field. Thus, optically-induced magnetization dynamics can be described by the Landau-Lifshitz equation.
