Where is the Magnetic Moment in CeB6

We performed the polarized neutron diffraction measurements in phase II of CeB 6 to observe the magnetic form factors. By the Maximum Entropy Method (MEM), we obtained the unexpected spin density distribution in CeB 6 . We clearly observed the existence not only at Ce site but also at between B 6 octahedral and at the center of triangle bonding in the B 6 octahedral. This is the first evidence that the magnetic moments are located between the Borons.
