Outline of Final Research Achievements

We succeeded to observe the magnetic excitation of the antiferromagnetic metal Cr up to under 300 meV. We found that the energy gap due to the formation of spin density wave appears in its magnetic excitation spectrum and that the magnetic scattering cross section of Cr can be qualitatively explained by the "spin unit model" proposed by this research team. In this study, other antiferromagnetic metals were also investigated, and the results supporting the possibility of the common magnetic excitation of the chimney structure existed were obtained. In anticipation of the investigation of ferromagnetic metals, which is the next step, we have grown large single crystals of ferromagnetic metals. Under the aim of technical development and dissemination of polarized neutron experiments for physical property research, we conducted device development and magnetic structure analysis by polarized neutron diffraction experiment.
