AB  - Magnetic skyrmions are two-dimensional, vortex-like spin states that carry a topological number. Due to their particle nature and emergent electromagnetic properties, skyrmions are viewed as promising candidates for information transport in future spintronics devices. A skyrmion can be described by the internal degrees of freedom of the spin configuration, termed helicity and vorticity. The two main types of skyrmions, Bloch and Néel-type, are characterized by the helicity , which is defined by the angle between the spin-modulation vector q and the spin-rotation plane [1]. Bloch-type skyrmions are characterized by a proper-screw type spin configuration with  = ±/2 (Fig. 1(a) and (b)) while Néel-type skyrmions have a cycloidal spin modulation with  = 0 or  (Fig. 1(c) and (d)). Recent studies have shown that this internal spin rotational form plays a key role in the current-induced control of skyrmions through spin-induced torques. To harness the spintronic functionalities of skyrmions, developing experimental techniques to determine the helicity is fundamentally important.
