  Taking the non-collinear antiferromagnetic hexagonal Heusler compound
Mn$_3$Ge as a reference system, the contributions to linear response phenomena
arising solely from the chiral coplanar and non-coplanar spin configurations
are investigated. Orbital moments, X-ray absorption, anomalous and spin Hall
effects, as well as corresponding spin-orbit torques and Edelstein
polarizations are studied depending on a continuous variation of the polar
angle relative to the Kagome planes of corner-sharing triangles between the
non-collinear antiferromagnetic and the ferromagnetic limits. By scaling the
speed of light from the relativistic Dirac case to the non-relativistic limit
the chirality-induced or topological contributions can be identified by
suppressing the spin-orbit coupling.
