Here, we present, for the first time, the spin density distribution of CeB6, isostructural with CaB6, deduced by the maximum entropy method (MEM) using polarized neutron diffraction (PND) data. Surprisingly, it reveals the presence of significant amounts of localized spin moment at non atomic sites between the nearest-neighbor boron atoms and the center of the triangle surface in the B6 octahedron network, in addition to the negative spin moment in the center of the B6 octahedron.
