Sign change of anomalous Hall effect and anomalous Nernst effect in the Weyl semimetal CeAlSi

MS Alam, A Fakhredine, M Ahmad, PK Tanwar… - Physical Review B, 2023 - APS
We report the anomalous Hall effect (AHE) and the anomalous Nernst effect (ANE) data for
the noncollinear Weyl semimetal CeAlSi. The anomalous Hall conductivity (σ ij A) was …
