Comment on arXiv:2510.13767; Structural origin of resonant diffraction in RuO2 (DOI: 10.1103/yr5q-1v1s)
Abstract
Occhialini et al. (arXiv:2510.13767; DOI: 10.1103/yr5q-1v1s) add results to several recent experimental studies of bulk magnetism in the rutile compound RuO2. It is of interest as a candidate altermagnet. The cited publication contains several serious errors. Notably, scattering amplitudes used to interpret measurements accomplished with resonant x-ray Bragg diffraction, which appear in the main text and SM (Eqs. 14 & 16), are wrong. The authors tender erroneous amplitudes (Phys. Rev. Lett. 122, 017202) and thereby ignore previously published correct results (Phys. Rev. B 105, 014403). As a result, the concluding statement and Footnote SM [54] are misleading.
