Abstract

All interpretations of extensive magnetic neutron scattering data in the cited paper are at fault [Phys. Rev. X 12, 021015]. For, the expressions for scattered intensities therein do not contain the cerium multipole whose likely contribution to the magnetic state of the pyrochlore is a principal goal of the published investigation. The Comment includes a brief look at essential corrections to the theory.
