Query: Magnetic Fluctuations of Filled Skutterudites Emerging in the Transition
  Region between Singlet and Triplet States   In order to clarify magnetic properties of filled skutterudites, we analyze
the Anderson model including seven $f$ orbitals hybridized with an $a_{\rm u}$
conduction band using a numerical technique. For $n$=2 corresponding to
Pr-based filled skutterudites, where $n$ is the local $f$-electron number, even
if the ground state is a singlet, there remain significant magnetic
fluctuations from a triplet state with a small excitation energy. This result
can be understood by the fact that $f$-electron states are clearly
distinguished as itinerant and localized ones in the filled skutterudite
structure. This picture also explains the complex results for $f$-electron
magnetic susceptibility and entropy for $n$=1$\sim$13.
