Due to the symmetry of the dipolar field of the tip, in addition to the collinear structure a magnetic vortex structure becomes stable. It is robust against excitations caused by the motion of the tip. We show that for high excitations the system may perform a transition between the two states. The influence of domain walls, which may also induce this transition, is examined.","authors_text":"Alfred Hucht, Dietrich E. Wolf, Haye Hinrichsen, Martin P. Magiera, Silvio R.
