| Research Abstract |
We developed a principled method for simultaneous determination under pressure of four values of transport properties: qualitative thermal conductivity and specific heat in addtion to electrical resistivity and thermopower.
For Eu compounds, we grew single crystals and studied their electronic properties and searching for pressure-induced phase transition by measuring the de Haas van Alphen effect and pressure effect. We clarified pressure-induced valence transition above 6 GPa and observed a plausible emergence of the CDW under pressures for EuGa4. The nesting effect might be realized for peculiar quadratic prism-like Fermi surface and drive CDW in EuGa4. We reported that measured the thermal expansion, magnetic susceptibility, specific heat, and thermopower, and formed heavy fermion state in EuNi2P2.
