Abstract:
We present the experimental magnetization reversal of artificial magnetic skyrmions in a Co/Pt multilayer film with perpendicular magnetization by a magnetic force microscope probe. The sample was a Co/Pt film containing an array of cylindrical regions with reduced anisotropy, which were modified by a focused He+ ion beam. The magnetic state of the sample was monitored by magnetic force microscopy. The local magnetization reversal was performed by the field of magnetic force microscope probe passing over the sample at low height. The effects of magnetostatic interaction between the probe field and skyrmion magnetization in these structures are investigated by micromagnetic simulations.
Keywords:
magnetic force microscopy, magnetic skyrmion, magnetization reversal effects, micromagnetic simulation.
