Gd substitution in DyB2C2 enhances the antiferromagnetic (AFM) interaction and weakens the antiferroquadrupolar (AFQ) interaction. In Dy0.8Gd0.2B2C2, two successive transitions occur. By performing resonant X-ray scattering measurements, we confir...

We have performed resonant and non-resonant X-ray scattering on GdB6 to investigate the two successive phase transitions at TN=?15K and T*=?10K. Below TN, new superlattice reflection at the wave vector [141412], which is the same wave vector deter...

Experimental evidence of the d-f Coulomb interaction responsible for the resonant x-ray scattering (RXS) from antiferroquadrupolar order in DyB 2C 2 is presented. The energy dependences of the RXS intensity with polarization analysis are analyzed ...

Resonant X-ray scattering study was carried out to investigate an anomalous ordered state (TA = 6.5 K.) in the filled skutterudite PrFe4P12. At the Pr-LIII absorption edge, we observed resonant features in h + k + l = odd reflections, which are fo...
