(a) The derivative relation. Field dependence of \(\rho _{xx}\) is given in absolute units and field dependence of \((d\rho _{xy}/dB)B\) is scaled to fit the \(\rho _{xx}\). (b) Field dependence of \(\sigma _{xy}\), the red, dashed line is the result of fit to the Eq. (1), which implied the fixed chemical potential of charge carriers. The red, dotted lines mark the values of quasi-quantized Hall conductance for \(\nu =1\) and \(\nu =2\) LL occupancy. The green dotted line marks the contribution from \(\nu =0^{-}\) last spin-split Landau level. The dotted blue line shows the result of evaluation performed in conserved particle number regime. Both calculation routines are described in the main text.
