Polarized Neutron Diffraction Study of CoS 2 . I Magnetic Moment Distribution of CoS 2

The magnetic form factor of CoS 2 has been determined for 27 Bragg reflections by means of the polarized neutron diffraction technique. Fourier transform of the observed data shows that the magnetic moment is localized on cobalt atoms, and the moment distribution is aspherical around cobalt nuclei, and there is almost no magnetic moment delocalized in the region between cobalt atoms. The measured magnetic form factor agrees well with the calculated free ion form factor for Co 2+ . The comparison between calculated and measured magnetic form factors shows that the magnetic moment delocalized in the region between cobalt atoms is very small, 0.01 3 ±0.02 4 (µ B /CoS 2 ), compared with those in ferromagnetic 3 d -transition metals. It shows further that 69±4% of the unpaired 3 d electrons occupy e g orbitals on the basis of the point charge model for the cubic crystalline field.
