Comment on "Scaling of the anomalous Hall effect in Sr(1-x)Ca(x)RuO3"

TL;DR

This paper critiques a previous study's interpretation of the anomalous Hall effect in SrRuO3, arguing that the scaling analysis does not support the intrinsic Berry phase explanation.

Contribution

It challenges the interpretation that the AHE in SrRuO3 is intrinsically due to Berry phase monopoles, providing a critical perspective on the scaling approach.

Findings

The scaling does not support the Berry phase monopoles interpretation.

The critique questions the intrinsic nature of the AHE in SrRuO3.

Highlights the need for alternative explanations of the AHE.

Abstract

We argue that the scaling of the anomalous Hall effect (AHE) by Mathieu et al. [Phys. Rev. Lett. 93, 016602 (2004)] does not provide support to the interpretation of the AHE in SrRuO3 as an intrinsic effect due to Berry phase monopoles in k-space.
