Abstract
We have made an extensive study of ${\text{PrB}}_{6}$ using x-ray resonant scattering to investigate both the lattice and magnetic properties. We have identified a structural distortion associated with the incommensurate to commensurate magnetic phase transition at $T=4.5\text{ }\text{K}$. Magnetic satellite reflections have been observed in the incommensurate and commensurate phases. The azimuthal dependence of the scattered intensity from the commensurate magnetic satellite reflection at $(\frac{1}{2},\frac{5}{4},\frac{5}{4})$ is consistent with the model for the magnetic structure deduced from earlier neutron-diffraction results. Evidence for possible quadrupolar ordering is discussed.
