abstract = {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.},
