The Landau free-energy of a compound that benefits from a linear coupling of an electric field and a magnetic field includes a product of the two fields, one polar and time-even and one axial and time-odd. In ME compounds, expectation values of some

Structural and magnetic transitions in a double perovskite hosting $5{d}^{1}$ Re ions are discussed in the context of recently published high-resolution x-ray diffraction patterns [D. Hirai et al., Phys. Rev. Res. 2, 022063(R) (2020)]. Our symmetry-i

A theoretical study of Bragg diffraction by an enantiomorphic pair of structures should apply to patterns gathered on \ensuremath{\beta}-Mn using resonance-enhanced x-ray diffraction. The chiral polymorph of manganese, and structurally related compou

Cubic double perovskites that host heavy ions with total angular momentum $J$ = 2 can exhibit a singular magnetic state epitomized by a lone octupole and bulk ferro-type magnetism. It exists in the Chen-Balents Hamiltonian with a quadrupole interacti

Cerium electronic multipoles in trigonal symmetry viewed in magnetic neutron diffraction are investigated. Analytic expressions for all the magnetic multipoles, and radial integrals calculated with an established atomic code, are used to scrutinize a

Compulsory Dirac multipoles in the bilayer perovskite $\mathrm{C}{\mathrm{a}}_{3}\mathrm{R}{\mathrm{u}}_{2}{\mathrm{O}}_{7}$ are absent in published analyses of experimental data. In a first step at correcting knowledge of the magnetic structure, we
