| Research Abstract |
Spin Hall effect, a phenomena to produce a magnetized state by flowing electric current along the narrow wire, is expected to develop new spintronic devices. We have investigated the development of new rare earth based material systems experimentally and theoretically to realize spin-Hall effect devices. Thin films and artificial superstructures of rare earth based intermetallic compounds which are expected to exhibit large spin Hall effects were fabricated for the first time.
