| Research Abstract |
We looked for the quantum state at low temperature using new type of pressure cell. In ferromagnet UGe_2, we specified the position of quantum critical endpoint which appears under high pressure and magnetic field. This quantum critical endpoint recently attracts attention as a new type of critical point at zero temperature. We also investigated the pressure variation of the transition temperature of perovskite-Fe-based superconductors.
