1. Octupole order in Ce 0.7 La 0.3 B 6 probed by resonant X-ray scattering The azimuthal angle dependence observed in the resonant X-ray scattering in phase IV of Ce 0.7 La 0.3 B 6 is analyzed theoretically[1]. It is shown that the peculiar angle dependence observed in the E2 channel is consistent with the Γ 5u-type octupole order with principal axis along(More)
In strongly correlated electron systems, enhanced fluctuations in the proximity of the ordered states of electronic degrees of freedom often induce anomalous electronic properties such as unconventional superconductivity. While spin fluctuations in the energy-momentum space have been studied widely using inelastic neutron scattering, other degrees of(More)
1. Consequences of multipole orders in CeB 6 and Ce x La 1−x B 6 A minimal model for multipole orders in CeB 6 is proposed and calculated by mean field theory [1, 2]. Both quadrupole and magnetic ordered phases can be reproduced with one model. From the mean field result, degeneracy of quadrupole order parameter and strong spin-orbit coupling cause(More)
The tooth crown color space model was manufactured and the improvement of the color representation and communication on the dental clinic have been trying. The study of color discrimination by dentist and student viewing with the use of tooth crown color chips reported here in basic knowledge on the color sensitivity of human eye. The test card were 55 x 90(More)
