  We study magneto-transport in heterostructures composed of the van der Waals
antiferromagnet CrPS$_{4}$ and the heavy metals Pt and Pd. The transverse
resistance (R$_{xy}$) signal reveals the spin-flop transition of CrPS$_{4}$ and
a strongly enhanced magnetic ordering temperature (>300 K), which might
originate from a strong spin-orbit coupling at the interface. While
CrPS$_{4}$/Pt devices allow for easy detection of the spin-flop transition,
CrPS$_{4}$/Pd devices show a more substantial enhancement in magnetic ordering
temperature and exhibit a topological Hall effect signal, possibly related to
chiral spin structures at the interface. The longitudinal magnetoresistance
(R$_{xx}$) results from a combination of spin-Hall magnetoresistance and the
negative magnetoresistance that can be explained by a field-induced change of
the electronic band structure of CrPS$_{4}$.
