Nanocomposite Pr7.5Dy1Fe71Co15Nb1B4.5 ribbons were prepared by melt-spinning and subsequent annealing. Interaction domains were imaged using magnetic force microscopy (MFM) because of strong exchange coupling between hard and soft magnetic grains. Coercivity was determined by exchange coupling pinning field. But the magnetization reversal of nanocomposite magnets were different from that of traditional single phase permanent magnets.

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.
