Temperature Dependence of the Field Induced Magnetic Form Factor of the Intermetallic Compound PrSn sub 3

摘要

The spatial distribution of the magnetization induced by a magnetic field of 42.5 kG in a single crystal of PrSn sub 3 has been studied at 100 and 20 K using polarized neutron scattering techniques. At both temperatures the measured form factor is in good agreement with the theoretical 4f magnetic form factor of the Pr exp 3+ ion. This result is in contrast to the large deviations from the 4f magnetic form factor of Ce exp 3+ observed, at low temperature, for the mixed-valence compounds CeSn sub 3 and CePd sub 3 . The localized static susceptibility of PrSn sub 3 at 100 and 20 K, obtained by extrapolating the measured form factor to the forward direction, agrees very well with bulk susceptibility measurements.
