Abstract

We performed inelastic neutron scattering spectroscopy on the Heusler intermetallic compound UPd UPd ₂Sn. The presence of a clear intramultiplet transition between the two lowest-lying 5 f electronic states of uranium was clarified, and is consistent with predictions made in the framework of a localized-electron model. The excess molar specific heat is well reproduced by a Schottky curve corresponding to the experimentally measured energy gap if a moderately enhanced electronic contribution is taken into account.
