Research Abstract |
In rare-earth and actinide compounds, various kinds of electronic ground states such as magnetic ordering, heavy fermion, and unconventional superconductivity are realized as a result of the competition between the RKKY interaction and the Kondo effect. In this research, electronic properties of several Ce- and Yb- compounds are investigated under high pressure, high magnetic field, and low temperature. Physical properties of pressure induced heavy fermion superconductors such as CePtSi_2, CeRhGe_2, and CePd_5Al_2 as well as a non-centrosymmetric compound CeIrGe_3 have been investigated. It is also found that YbIr_2Zn_<20> exhibits an extremely heavy fermion state under high pressure near the quantum critical point.
