Response to "Comment on Ferroelectrically induced weak ferromagnetism by design," by R. de Sousa and J. E. Moore, arXiv:0806.2142

TL;DR

This paper refutes a recent comment claiming a duality in ABO3 materials, clarifying that the comment's crystallographic errors invalidate its critique of the original work on ferroelectrically induced weak ferromagnetism.

Contribution

The authors correct misconceptions in the comment, reaffirming the validity of their original findings on ferroelectric and magnetic coupling in ABO3 materials.

Findings

The comment contains three crystallographic errors.

The duality between A-site and B-site is maintained.

Original conclusions on ferroelectric-magnetic coupling remain valid.

Abstract

A recent Comment [arXiv:0806.2142] has argued that "there is a simple duality between A-site and B-site" R3c ABO$_3$ materials and that our Letter [PRL 100, 167203 (2208)] "breaks this duality by ignoring a non-polar distortion that is directly measured in crystallography." Here we point out that this is not correct. The Comment contains three elementary crystallographic errors. In this response we address each error in some detail.
