摘要：

The ultrashort, pulsed laser excitation of a half-metallic, ferromagnetic CrO2 thin film was used to directly trigger coherent transient magnetization rotation on a subnanosecond time scale. By applying the photoexcitation in pairs of time sequenced pump pulses, the phase of the transient precession of the magnetization vector was manipulated.
