摘要：

The symmetry property and characteristic momentum dependence of elastic neutron scattering spectra due to ordered magnetic octupoles in f-electron compounds are studied theoretically. In particular, it is shown through a form factor analysis of Ce1-xLaxB6 that a recent observation by Kuwahara et al. [J. Phys. Soc. Jpn. 76 (2007) 093702] is interpreted as a realization of such a novel scattering mechanism. A possible neutron scattering by field-induced octupoles in the quadrupolar phases is also discussed.
