WebJun 5, 2024 · It was discovered in a chiral magnet, MnSi with B20 structure, in 2009 and later confirmed as a common feature of magnetic compounds with Dzyaloshinsky–Moriya interaction (DMI). In this work, we provide fundamental insight into the magnetic properties of skyrmion-hosting materials originating from DMI. WebChiral bobbers: (a) traditional spin bobber and (b) chiral spin bobber in hard-soft magnetic bilayers. In (b) the blue region is a Co-Fe alloy and the yellow region is MnBi.

WebDec 13, 2024 · According to the simulation results, we find that both the tube-like Néel-type skyrmions and the bobber-like Néel-type skyrmions can be electrically generated. In particular, the size of the bobber-like Néel-type skyrmions can be effectively reduced by the spin-orbit torques, which leads to the formation of 20 nm Néel-type skyrmions.
