Non-anomalous magnetization density distribution in CeB₆

Results of polarized neutron diffraction on the compound CeB 6 are used to obtain its magnetization density distribution. The measurements are performed at two different points of the magnetic phase diagram (phase I and II). The data are analysed in direct space using the maximum entropy method, as well as in reciprocal space using the cerium form factor expansion and anisotropy. The conclusion is that, in both phases, the magnetization is localized on the cerium sites only. This result is in contradiction to a recent paper by Saitoh et al (2002 J. Phys. Soc. Japan 71 2369), claiming that, in phase II, a localized spin moment was observed at non-atomic sites.
