摘要：
We measured the velocity of the flux front of an artificially nucleated dendritic instability in YNi2B2C. The required time resolution in the nanosecond regime was achieved by our magneto-optic pump-probe technique, utilizing a femtosecond laser system. The penetration velocity of the flux front is on the order of 360 km s(-1).
