Dynamic Elastoresistivity Evidence for Slow Nematic Fluctuations in BaFe$_2$As$_2$

TL;DR

This paper reports the correction of an instrumentation error in elastoresistivity measurements of BaFe2As2, showing that the previously observed frequency enhancement was an artifact, and the corrected data indicates frequency independence.

Contribution

The study clarifies that the earlier observed frequency enhancement was due to instrumentation issues, providing more accurate elastoresistivity data for BaFe2As2.

Findings

Original frequency enhancement was an artifact.

Corrected data shows frequency independence.

Instrumentation issues can significantly affect elastoresistivity measurements.

Abstract

An instrumentation problem with the signal acquisition at high frequencies was discovered and we no longer believe that the experimental data presented in the manuscript, showing a frequency enhancement of the elastoresistivity, are correct. After correcting the problem, the elastoresistivity data is frequency independent in the range investigated. Therefore, the authors have withdrawn this submission. We would like to thank Alex Hristov, Johanna Palmstrom, Josh Straquadine and Ian Fisher (Stanford) for the kind discussions and assistance we received which helped us identify these problems.
