interest. Previously, huge attention was paid to Bismuth-based material to incorporate
magnetic interactions in the parent topological compound by doping partially filled 3d/4f
elements or heterostructure engineering. Nowadays, the activeness of such work is diverted
toward the successors of the TI family, i.e., other potential topological materials, and some of
them are under scrutiny to implement magnetic heterostructure with topological protection.
In the present work, a heterostructure interface has been planned between a newly predicted.
Dirac semi-metal and layered ferromagnetic insulator with an acceptable lattice mismatch.
We have addressed the physical response, i.e., the exotic quantum anomalous Hall effect
(QAHE) driven by the Berry curvature using the first-principles density functional theory and
tuning it with a different type of heterostructure stacking. Our present study found that the
hybridization-driven magnetic proximity effect breaks the time-reversal symmetry at the
interface leading to QAHE. This work may be a guiding principle for designing
next-generation magneto-electric device applications.
