The temperature dependencies of the specific heat and the anisotropic magnetic susceptibility of the heavy-fermion superconductor UPd 2 Al 3 show distinct anomalies which can be described by a crystalline electric field (CEF) model for Uranium with hexagonal site symmetry. We find that a CEF-level scheme for the 3 H 4 multiplet ( 5f 2 configuration) implying two low lying singlets surprisingly well fits the experimental results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
