| Research Abstract |
The major goal of this project is to measure directly the ferromagnetic interactions in the ferromagnetic materials for the spintronics devices. Bulk materials mandatory for this specific purpose have been developed to be grown in the nonequilibrium condition by the mechanical milling method. At the same time, new neutron scattering method to measure spin wave scattering from powder materials has been completed by combining pulsed neutrons and high resolution chopper instrument installed at J-PARC.
