  The enhancement of interfacial Dzyaloshinskii-Moriya Interaction (DMI) in
magnetic multilayers results in the stabilization of topological spin textures
like chiral domain walls and skyrmions. Here we report on the evaluation of
interface-driven magnetic interactions in a uniquely designed multilayer where
each magnetic layer of two AFM coupled sublattices of 3d and 4f moments is
sandwiched between the layers of \beta-tungsten and holmium whose spin Hall
angles are large but opposite in sign. The atomic and magnetic periodicity of
these multilayers is established by polarized neutron reflectivity measurements
and the presence of a labyrinth domain spin texture of zero remanence with
x-ray photoelectron microscopy. Measurements of the Hall resistivity
(\rho_{xy}(T, H)) together with static magnetization (M(T,H)) over a broad
range of temperature (T) and magnetic field (H) indicate impending compensation
between 3d and 4f sublattices at T>350 K. These multilayers are characterized
by a small (0.04 %) but positive magnetoresistance indicative of interface
enhance scattering and a large (40 n\Omega.m) and negative anomalous
\rho_{xy}(T,H) which results from a parallel alignment of 4f moments with the
external magnetic field. No distinct scaling is seen between \rho_{xy}(T,H),
\rho_{xx}(T, H) and M(T,H) at temperatures above 200K where the magnetization
develops out-of-plane anisotropy. The field scans of \rho_{xy} at T>200K show a
distinct cusp in the vicinity of magnetic saturation. These Hall data have been
analyzed in the framework of a model where a distinct topological contribution
to \rho_{xy} rides over the anomalous Hall resistivities of the 3d and 4f
magnetic sublattices. It is suggested that this apparent topological effect
results from an interfacial DMI and dominates \rho_{xy}(T,H) in the temperature
regime where the 3d and 4f lattices are nearly compensated.
