a, b, Local longitudinal resistance \({R}_{\mathrm{xx}}\) at \(T=1.6\) K as a function of \(\nu\) and \(E\) at \({B}_{\perp }=0\) T (a) and 14 T (b). Holes are shared in both layers inside the region bounded by the orange dashed lines. The Kondo lattice regime is bounded by the blue lines. c, d, Dependence of \({R}_{\mathrm{xx}}\) (c) and normalized Hall density \({n}_{{\rm{Hall}}}/{n}_{{\rm{M}}}\) (d) on \({B}_{\perp }\) at varying \({\nu }_{{\rm{c}}}\) with \({\nu }_{{\rm{f}}}=1\) (\(T=1.6\) K). Arrows in c denote the critical field \({B}_{\perp {\rm{C}}}\). Above \({B}_{\perp {\rm{C}}}\), the Hall density in d reveals the carrier density of the decoupled W-band. e, Local or bulk resistance as a function of temperature. The dashed line denotes the expected quantized value. f, Magnetic-field dependence of \({R}_{\mathrm{xx}}(0\,{\rm{T}})/{R}_{\mathrm{xx}}(B)\) at 1.6 K. Strong magnetoresistance is observed only for the TKI under an in-plane field.
