We theoretically study the interplay between magnetism and a heavy Fermi liquid in AB stacked transition metal dichalcogenide bilayer system MoTe$_2$/WSe$_2$ regime which Mo layer supports localized magnetic moments coupled by interlayer electron tunnelling to weakly correlated band of itinerant electrons W layer. show that transfer leads chiral Kondo exchange, with consequences including strong dependence temperature on carrier concentration, topological hybridization gap an anomalous Hall effect. The theoretical model exhibits two phases, small surface magnet large liquid; them is first order. A low-energy theory developed for transport properties states. Implications our results present future experiments heterostructures are discussed.
