Reply to the Comment by S. Wirth et al. on "Tuning low-energy scales in YbRh$_2$Si$_2$ by non-isoelectronic substitution and pressure"

TL;DR

This paper refutes claims that Hall measurements invalidate previous findings on the Kondo breakdown in YbRh₂Si₂, clarifying the effects of doping and pressure on its low-energy scales.

Contribution

It provides a detailed analysis and rebuttal of criticisms regarding the interpretation of the $T^*(B)$ crossover in YbRh₂Si₂, reaffirming the original conclusions.

Findings

Hall data do not contradict previous interpretations

Doping and pressure effects on $T^*(B)$ are consistent with Kondo breakdown

The comment's criticisms are addressed and refuted

Abstract

Previously, we reported that the doping and pressure dependence of the $T^\ast(B)$ crossover in YbRh$_2$Si$_2$ is incompatible with its interpretation as signature of a Kondo breakdown [M.-H. Schubert et al., Phys. Rev. Research 1, 032004(R) (2019)]. The comment by S. Wirth et al. [arXiv:1910.04108] refers to Hall measurements on undoped YbRh$_2$Si$_2$ and criticizes our study as incomplete and inconclusive. We thoroughly inspect these data and rebut the arguments of the comment.
