摘要:
In the present experiment polarized neutron scattering techniques have been used to assess the spatial distribution and temperature dependence of the magnetization induced in asinglecrystal of &ggr;‐Ce by a magnetic field of 60 kG. The measured form factor is found to be in agreement with the free ion 4fmagnetic form factor of Ce3+. Comparison of the localized susceptibility, obtained in the present experiment, with bulk susceptibility measurements indicate that there is a rather large positive conduction electron contribution to the static susceptibility of &ggr;‐Ce. The localized moment is found to follow, between 300 and 115 K, a Curie‐Weiss law with a paramagnetic Curie temperature of (−44±2.5) K. The measurements indicate that at approximately 100 K some ions of the &ggr;‐Ce crystal undergo a change in their electronic configuration.
