Magnetic neutron scattering on the intermediate valence system CePd/sub 3/
- Kernforschungsanlage, Juelich, Ger.
CePd/sub 3/ is an intermediate valence intermetallic compound /1,2/ fluctuating between a nonmagnetic Ce/sup 4 +/ (4f/sup 0/, J = 0) and a magnetic Ce/sup 3 +/ (4f/sup 1/, J = /sup 5///sub 2/) state. Measurements of the diffuse neutron scattering cross-section with TOF-analysis at several angles in the temperature interval 3.5 to 300/sup 0/K are reported. A quasielastic magnetic line with 4f formfactor is found along with an abnormally large, nearly temperature independent width (GAMMA/2 = 18+- 2 MeV at 240/sup 0/K). The lower the temperature the more the measured magnetic cross-section is reduced compared with the value calculated on the assumption that all Ce-ions are in the 4f/sup 1/ (Ce/sup 3 +/) state (Curie-susceptibility). However, the cross-section is consistent with the actually measured, nearly temperature independent static susceptibility.
