Flux waves in Bi2Sr2CaCu2O8+d crystals

 

2D Magneto optical images of part of the sample taken at 24 K immediately after application of 430 Oe.

 

 

    Direction of flux motion (entering the sample due to relaxation)

     Direction of "waves"

 

The following movie shows a sequence of 2D Magneto optical images of the entire sample width taken at 24 K immediately after application of 430 Oe.

 

 

The time evolution of an induction profile B(x), taken across the sample.
Here we zoom on the left side of the sample – showing the waves

                  

Induction profiles B(x) across the entire sample width at various times between 0.3 and 1.5 s. The square marks the region which is enlarged.
