| Research Abstract |
In 4f-electron systems, including rare-earth elements, various kinds of magnetic and orbital ordering have been found. In addition to dipole and quadrupole ordering, in recent years the possibility of higher-order multipole ordering has been also discussed for several materials, including filled skutterudite compounds. In this study, we have carried out experimental studies for possible multipole orderings in filled skutterudite compounds and observed anomalous behaviors of several compounds. Furthermore, we have succeeded to synthesize four new filled skutterudite compounds.
