A case for Bragg diffraction by a noncollinear (PT)-symmetric antiferromagnet Cu(MoO)(SeO)
S. W. Lovesey, G. van der Laan
Antiferromagnetic compounds chromium sesquioxide (CrO) and dioxomolybdenum selenite present linear magnetoelectric effects. Anti-inversion symmetry in the corresponding mag…

Magnetic symmetries of terbium tetraboride (TbB4) revealed by resonant x-ray Bragg diffraction
R. D. Johnson, S. W. Lovesey
A recent experimental study of TbB4 at a low temperature using resonant x-ray Bragg diffraction implies a magnetic symmetry not found in any other rare-earth tetraboride. The evide…

Magnetic properties of Sohncke-type Pb(TiO)Cu4(PO4)4
S. W. Lovesey
The enantiomorphous (chiral) crystal class of the Sohncke-type insulator Pb(TiO)Cu4(PO4)4 permits the rotation of the plane of polarization of light (optical activity). Copper ions…
