摘要：

We have made an extensive study of PrB6 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 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 (1/2, 5/4, 5/4) is consistent with the model for the magnetic structure deduced from earlier neutron-diffraction results. Evidence for possible quadrupolar ordering is discussed.
