| Outline of Final Research Achievements |
In order to reveal pressure-induced magnetic phases on the cerium-based heavy electron superconductor CeNiGe3, we developed a small pressure cell with a wide detectable reflection angles for neutron diffraction experiments. For higher-pressure experiments above 4 GPa, further improvement on the gasket and sealing parts is indispensable. High-pressure neutron experiments were late because of a delay on the development of high pressure cell and a trouble on the cryostat in the neutron facility. Under these circumstances, we studied an alternate research subject of the noncentrosymmetric cerium-based intermetallic compounds CePdSi3. For CePdSi3, we found multiple magnetization steps, complex magnetic phase diagrams, and a possibility that an incommensurate magnetic ground state is realized.
