Abstract

Antiferromagnetic compounds chromium sesquioxide (Cr $_{2}$ O $_{3}$ ) and dioxomolybdenum selenite present linear magnetoelectric effects. Anti-inversion symmetry in the corresponding magnetic crystal classes dictate the makeup of magnetic Bragg diffraction patterns. Copper axial and polar magnetic multipoles contribute to resonant x-ray and magnetic neutron amplitudes in a symmetry informed analysis of monoclinic Cu $_{2}$ (MoO $_{4}$ )(SeO $_{3}$ ) presented with a view to steering future diffraction experiments. The compound might be viewed as a low-dimensional quantum magnet on account of its crystal structure and extreme Cu spin (S = 1/2).
