Comment on "Altermagnetic and Dipolar Spitting of Magnons in FeF_2" arXiv:2601.04303
S. W. Lovesey
Conclusions by Sears et al. (arXiv: 2601.04303) about dispersions of magnons in rutile FeF_2 are unsound because compulsory lattice vibrations are omitted in the analysis of their…
Magnetic structure of diamond EuTi2Al20
S. W. Lovesey, D. D. Khalyavin
We study magnetic symmetries of EuTi2Al20 that appear in the ordering of Eu ions below a temperature at 3.3 K, according to an analysis of substantial experimental evidence [M. Kaw…
Comment on arXiv:2510.13767; Structural origin of resonant diffraction in RuO_2 (DOI: 10.1103/yr5q-1v1s)
Stephen W. Lovesey
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 RuO_2. It is of interest as…
Chiral magnetnetism in an altermagnet (MnF2)
Stephen W. Lovesey
Symmetry informed diffraction patterns for magnetically ordered MnF2 illuminated by x-rays tuned in energy to a Mn atomic resonance depend on circular polarization in the primary b…
A case for resonant x-ray Bragg diffraction by a collinear antiferromagnet Li2Ni3P4O14
Stephen W. Lovesey
Magnetic axial and polar (Dirac) nickel multipoles contribute to resonant x-ray Bragg amplitudes in a symmetry informed analysis of monoclinic Li2Ni3P4O14 presented for future diff…
EuPdSn2; magnetic structures in view of resonant x-ray Bragg diffraction
Stephen W. Lovesey
The magnetic properties of materials hosting Eu2+(J = 7/2, 4f7) ions have attracted much attention in the science of strongly correlated electrons. In part because crystal electric…
