a, b, \({R}_{\mathrm{xx}}\) (a) and \({R}_{\mathrm{xy}}\) (b) as a function of \(\nu =1+{\nu }_{{\rm{c}}}\) and \({B}_{\perp }\) with νc varying along the arrow direction shown in Fig. 2a (\(T=1.6\) K). The dashed lines mark the critical field \({B}_{\perp {\rm{C}}}\) to fully polarize the iterant hole spins and the local moments. SdH oscillations emerge above \({B}_{\perp {\rm{C}}}\), at which \({R}_{\mathrm{xy}}\) changes sign. c, d, Dependence of \({R}_{\mathrm{xx}}\) (c) and the 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). The 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. (The results are from device 1.).
