2AHE model analysis of the hump structure of the CT/BSTS heterostructure. a Separation of \({\rho }_{AHE}\left(H\right)\) into the \({\rho }_{AHE}^{pos}\) and \({\rho }_{AHE}^{neg}\) at T = 50 K. b, c \({\rho }_{AHE}^{pos}\) (b) and \({\rho }_{AHE}^{neg}\) (c) with varying the temperature in the range of 50–90 K. d, e The coercive fields (\({H}_{c}^{pos \left(neg\right)}\)) (d) and the amplitude of anomalous Hall resistivities (\({R}_{pos \left(neg\right)}\)) (e) of the negative (green) and the positive (yellow) AHE as a function of temperature. f Plot of \({R}^{pos}\) as a function \({\rho }_{CT}\), showing the linear dependence of \({R}^{pos}\propto {\rho }_{CT}\). g Log-log plot of \({R}^{neg}\) vs. \({\rho }_{BSTS}\), showing the power law dependence of \({R}^{neg}\propto {\rho }_{BSTS}{)}^{1.8}\)
