摘要
Under zero magnetic field, antiferro-quadrupole ordering in CeB6, has been observed for the first time by means of resonant x-ray scattering(RXS) technique. The RXS is observed at, the 2p -> 5d dipole transition energy of the Cu L-3-edge. A possibility of determination of the various type of the induced quadrupole ordered state at, (1/2, 1/2, 1/2) is also discussed on the basis of the model calculation of azimuthal anlge dependence of the RXS intensity,
