| Outline of Final Research Achievements |
To clarify the mechnisim of magnetization reversal, we made Pt/Co/Pt structures with inversion symmetry and and AlO/Co/Pt structures with inversion asymmetry. In Pt/Co/Pt structures, we succeeded in evaluating conversion relation between current and magnetic field induced by spin Hall effect. We found that both Rashba and spin Hall effects coexist in AlO/Co/Pt structures. The Rashba effect is dominant with increasing Co thickness while the spin Hall effect is getting larger with increasing Pt thickness.
