Switching of a rectangular 'soft' magnetic element

Simulated transient magnetization dynamics for a square-shaped Py element with lateral sizes 4 x 4 μ2 and the thickness 50 nm after the field pulse applied perpendicular to the element plain (the element magnetization was in the so called Landau closed configuration before the pulse). Strong magnetization oscillations of the domain walls during and after the field pulse can be seen.
