Incommensurate and commensurate quadrupole orders in Ce0.7Pr0.3B6

Abstract Non-resonant X-ray diffraction experiments were performed on Ce 0.7 Pr 0.3 B 6 . We have found superlattice reflections for commensurate n 2 n 2 n 2 , where n are odd integers and incommensurate h ± 2 δ k 2 l , where h and l are integers, and k are odd integers, at the low temperature phases in zero magnetic field.
