Magneto-optic Investigation of Magnetic Flux Penetration on a Nanosecond Timescale

Abstract

We have studied the dynamics of iron-garnet films using a pump-probe technique and were able to demonstrate that the response time of such a film is sufficiently short to investigate sub-nanosecond phenomena. Furthermore, we studied the penetration velocity of the dendritic instability in thin YBCO films. We found two regimes: An early stage with a penetration velocity of up to 17Okmls and a distinct later stage were the velocity is lower (= 18 km/s).
