Fig. 8: Selective delivery of a set of skyrmions by the field polarity.
From: Skyrmion motion and partitioning of domain wall velocity driven by repulsive interactions
a In such configuration, a domain wall sits in between two sets of skyrmions. b, c A perpendicular magnetic field (H) in a given direction will shift only one set of skyrmions in a certain direction without affecting the other set. Note that, one skyrmion or more can be included in each set. The strengths of perpendicular magnetic anisotropy and Dzyaloshinskii-Moriya interaction are Ku = 0.8 MJm−3 and D = 3.5 mJm−2, respectively. The field strength is H = 500 Oe and t is the action time of field.
