| Outline of Final Research Achievements |
It has been investigated the properties of superconducting states of anti-ferromagnetic heavy fermion system under high pressure by heat capacity measurements. We shed light on the non-inversion symmetry compounds CeRhSi3 and CeIrSi3 and typical pressure induced superconductor CeRhIn5 and CeIn3. In all compounds, we found the increasing phenomena in heat capacity at Quantum Critical Points (QCP). These results suggest the states of the Non-Fermi-Liquid (NFL) and/or the Spin Fluctuation (SF) appeared universally. The increasing of the NFL and/or the SF at QCP plays important role creating the Cooper Pair in these compounds. Moreover, p or d symmetry superconducting states (the anisotropic superconducting gap) would be appeared in this system by the observation of heat capacity measurements in the rotation magnetic fields.
