The magnetization reversal in Permalloy (Py) and Py-IrMn disks (1μm diameter) is investigated. The Py disks reverse their magnetization via vortex state formation. Conversely, if the Py-IrMn disks are field cooled from above the blocking temperatureTB, a critical angle with respect to the cooling direction is set, beyond which the vortex no longer nucleates.
