FeCoSiB_reversal_big

Magnetization reversal in an annealed ferromagnetic FeCoBSi layer around the coercive field

Color-coded angular distributions of magnetization before and after the magnetic switching event together with the corresponding magnetic vector plots. Complementary Kerr images with orthogonal sensitivity directions are shown. The difference ∆ of magnetization for different sensitivity directions during switching is shown.
