  Tailoring the quantum many-body interactions in layered materials through
appropriate heterostructure engineering can result in emergent properties that
are absent in the constituent materials thus promising potential future
applications. In this article, we have demonstrated controlling the otherwise
robust magnetic properties of transition metal phosphorus trisulphides
(Mn/Fe/NiPS3) in their heterostructures with Weyl semimetallic MoTe2 which can
be attributed to the Dzyaloshinskii Moriya (DM) interactions at the interface
of the two different layered materials. While the DM interaction is known to
scale with the strength of the spin-orbit coupling (SOC), we also demonstrate
here that the effect of DM interaction strongly varies with the spin
orientation/dimensionality of the magnetic layer and the low-energy electronic
density of state of the spin-orbit coupled layer. The observations are further
supported by a series of experiments on heterostructures with a variety of
substrates/underlayers hosting variable SOC and electronic density of states.
