Abstract

The magnetic form factors of Ce ions in CeP have been studied by unpolarized and polarized neutron diffraction. The measured form factor in the type-I antiferromagnetic phase (H = 0 and T = 2 K) agrees with the calculation for a Γ7 crystal-field pound state. On the contrary, the data at H = 3 T and T = 1.7 K (in the so-called 'phase I') and that at H = 5.5 T and T = 12 K (in 'phase III') indicate that the Ce ions with large moments appearing in these structures are in a strongly polarized state very close to the crystal-field state Γ8. This result supports the view that a Γ8-like wave function is stabilized by the formation of a magnetic-polaron state.
