Abstract

Superlattice reflections in the multipole ordered phase of PrRu 4P12 and Pr(Ru0.97Rh0.03) 4P12 has been measured using a synchrotron x-ray scattering technique. The Thomson scattering intensity of (111) at 1.7 K does not show significant variation with magnetic field up to 7 T in contrast to the reported variation of electrical resistivity. This means that the lattice distortion in the ordered phase is robust and the staggered ordering remains after split of triplet ground state at half of Pr sites. The nonmetallic staggered ordering is not destroyed completely by applying magnetic field. Energy scan at (111) reflection of Pr(Ru0.97Rh0.03) 4P12 show temperature dependence around resonant energy of Pr L3 edge. This may allow us to observe anisotropy of electronic ordering of Pr sites and gives us a hint for direct observation of higher rank multipole order in PrRu4P12.
