Abstract

We have performed the resonant x-ray scattering experiment on DyB 2C2 and H0B2C2, where the antiferroquadrupolar orders play important roles. The superlattice reflections that appear below the transition temperatures have been investigated by measuring the incident energy, polarization, scattering vector, azimuthal angle and temperature dependences at the L3 absorption edge. The results are theoretically analyzed with a model of the antiferroquadrupolar order: the azimuthal angle dependences are well explained. The quadrupolar and magnetic contributions to the scattering intensities are also separated: it is deduced that the magnitude of the ordered quadrupolar moments of H0B2C 2 is much smaller than that of DyB2C2.
