Incommensurate and commensurate quadrupole orders in Ce 0.7Pr 0.3B 6

Non-resonant X-ray diffraction experiments were performed on Ce _0.7Pr _0.3B ₆. We have found superlattice reflections for commensurate {n}/{2} {n}/{2} {n}/{2}, where n are odd integers and incommensurate h±2δ {k}/{2} l, where h and l are integers, and k are odd integers, at the low temperature phases in zero magnetic field.
