Abstract

Resonant x-ray scattering experiments show that a pyrochlore iridate exhibits all-in all-out ordering---the moments either all point towards the center of the crystal unit cell, or away from it---which is a prerequisite for stabilizing a Weyl semimetal phase. This suggests that some pyrochlore iridates may behave as Weyl semimetals.
