Reply to Comment by Borisenko et al. on article `A de Haas-van Alphen study of the Fermi surfaces of superconducting LiFeP and LiFeAs'

TL;DR

This paper defends the original interpretation of de Haas-van Alphen measurements on LiFeAs, arguing against Borisenko et al.'s alternative magnetic breakdown explanation and reaffirming the inconsistency with ARPES surface bands.

Contribution

The paper provides a rebuttal to a comment disputing the interpretation of Fermi surface measurements, reaffirming the original conclusions based on experimental data.

Findings

Original dHvA measurements are inconsistent with surface ARPES bands.

Magnetic breakdown scenario does not fit the experimental data.

The original interpretation of the Fermi surface remains valid.

Abstract

Recently, Borisenko et al have posted a Comment (arXiv:1108.1159) where they suggest an alternative interpretation of our de Haas-van Alphen (dHvA) measurements on the superconductor LiFeAs. In our original paper (arXiv:1107.4375) we concluded that our measurements of the bulk Fermi surface were not consistent with the surface bands observed thus far by ARPES. Borisenko et al dispute this and suggest the two measurements are consistent if some of the orbits we observe are due to magnetic breakdown. We argue here that this scenario is inconsistent with the experimental data and therefore that our original conclusion stands.
