Summary

[edit]
Description Magnetization configuration of skyrmions (Q = 1) and antiskyrmions (Q = −1) with fixed polarity (p = 1) and varying helicity. The length and direction of the arrows represent the in-plane component of m, and the color indicates mz. A Néel skyrmion with Q = 1 and helicity γ = 0 corresponds to DMI with C∞v symmetry. A Bloch skyrmion with Q = 1 and helicity γ = π/2 corresponds to DMI with SO(3) symmetry. Antiskyrmion with Q = −1 and helicity γ = 0 corresponds to DMI with D2d symmetry. An arbitrary helicity γ can be obtained via the global rotation arounds the z-axis by an angle γ. Antiskyrmions can be obtained from skyrmions by a reflection with respect to a plane perpendicular to the plane of the magnet
