| Research Abstract |
In PrRu4P12, we have found the formation of "4f-electron-nuclear hyperfine-coupled multiplets" (formed by the hyperfine interaction between the 4f electron magnetic moment and the nuclear spin in each of Pr ions). The multiplets form a lattice in the crystal without showing any magnetic orderings at least down to 20mK. In this research work, we have investigated low-temperature transport properties and have found anomalies, which indicate that the multiplets are strongly coupled with extremely-low-density conduction electrons to form an unconventional type of strongly correlated electron states. After an intensive search in rare-earth-based intermetallic compounds, we have found some candidate materials appropriate for the investigation of the physics of "4f-electron-nuclear hyperfine-coupled multiplets".
