| Research Abstract |
In general, 4f-electrons and 3d-electrons in materials have multi degrees of freedom on the orbital and the magnetic states. In a V oxide and a Pr intermetallic compound, which have comparable ordering energy between the orbital states or between the orbital and the magnetic state, it has been revealed by single-crystal neutron diffraction experiments that the particular orbital or the particular magnetic order has been reallized by controlling the balance between these ordering energy using high-pressure technique. In this study, new high-pressure techniques for single-crystal neutron diffraction experiments under 10GPa have been also developed successfully.
