  Among the vast magnetic heterostructures explored in Condensed Matter
Physics, two contrasting interpretations of the hump-shaped Hall Effects remain
ambiguous and debated, namely, the overlap of two opposite-signed
Karplus-Luttinger Hall loops associated with inhomogeneous collinear domains
with perpendicular anisotropy, or the Geometrical/Topological Hall Effect
emanated from hexagnal close-packed lattice of Skyrmion ground state with
smoothly varying non-collinear moments. Their similarity in topology implies
difficulty in discrimination via magnetic imaging. Here, this ambiguity is
overcome and clarified by the divergence exponent of hump peak fields extracted
from Hall measurements with magnetic field rotation on several
heterostructures. Their difference in sensitivity to in-plane fields reveals
that the former mechanism involves higher uniaxial anisotropy than the latter,
departing from the Skyrmion ground state regime by the Ginzburg-Landau
framework of triple-q spin-wave superposition. Numerous material systems can be
summarized into a single curve of divergence exponent versus the collinear
quality factor, bridging the crossover of the two mentioned mechanisms.
