| Fig.: Magnetization reversal of an assembly of
10 µm x 10 µm ferromagnetic GaMnAs dots, defined by
hydrogen passivation. The region outside the dots are passivated, paramagnetic GaMnAs. The movie is a series of snapshots, obtained by
Kerr microscopy at 50 K. They were acquired after
5s magnetic field pulses of increasing intensities. The dots are not
visible before reversal, since each snapshot was normalized with a
reference image taken at saturation. |
