Abstract

Local Hall magnetometry was applied to micron-sized NiFe rings. The magnetic transitions were investigated with high resolution. For narrow rings, a sharp transition between the onion and the vortex state was detected. LHE measurements at low temperatures and numerical simulations show that in rings with small holes local vortices are created and that the interplay between reversible and irreversible transitions rules by the hysteresis curve.
