  Experimental techniques using Bragg diffraction may elucidate electronic and
magnetic properties of ferric ions in multiferroic ScFeO3 that are puzzling. A
collinear magnetic motif of dipole moments is not expected for s-state ions
with an acentric parent (paramagnetic) structure, because single-site
anisotropy is negligible and antisymmetric exchange interactions promote an
inhomogeneous magnetic motif. However, current indications are that ScFeO3
supports G-type antiferromagnetism, with an unknown moment direction, which
implies that ferric ions are not in the high-spin 6S state. It is argued that
significant insight on these open questions can be achieved by confronting
experimental data with calculated structure factors for resonant x-ray and
magnetic neutron Bragg spots, and we report results for G-type
antiferromagnetism allowed by the corundum-like parent R3c structure.
Calculated structure factors include Dirac multipoles that are time-odd and
parity-odd, e.g., dipoles that are often called anapoles or toroidal moments.
