Fig. 4: Extrinsic nature of the anomalous Hall effect.
From: Dichotomy of magnetic effect between Weyl fermions and anomalous Hall effect in PrAlSi
a The calculated anomalous Hall conductivity. b, c Scaling relation of anomalous Hall effect for various materials. Panel b is the enlarged part of panel c and only displays the data of PrAlSi samples. The data of other materials were taken from references and therein40,51,52,53,54,55,56,57,58,59 in panel c. Purple lines represent three anomalous Hall ratios (\({\sigma }_{{AHE}}/{\sigma }_{{xx}}\)) and their corresponding anomalous Hall angles (\({AHA}={\tan }^{-1}({\sigma }_{{AHE}}/{\sigma }_{{xx}})\)). The data of Sample 2 is shown in Fig. 3 and that of Sample 1, 3–5 is shown in Supplementary Section V.
