Stabilizing zero-field skyrmions in Ir/Fe/Co/Pt thin film multilayers by magnetic history control
Stabilizing zero-field skyrmions in Ir/Fe/Co/Pt thin film multilayers by magnetic history control
We present a study of the stability of room-temperature skyrmions in [Ir/Fe/Co/Pt] thin film multilayers, using the First Order Reversal Curve (FORC) technique and magnetic force microscopy (MFM). FORC diagrams reveal irreversible changes in magnetization upon field reversals, which can be correlated with the evolution of local magnetic textures probed …
