Figure 2 (IMAGE) Institute for Basic Science Caption Dipole-quadrupole interference in circular dichroic resonant x-ray diffraction. (a) The spin quadrupole moments are formed at a higher temperature (263 K) than the magnetic moments (230 K). (b, c) At low temperatures, the interference between the spin quadrupole and the magnetic moments is manifested by circular dichroic resonant X-ray diffraction, a magnetic signal difference between left- and right-handed X-ray beams.
