| Outline of Final Research Achievements |
From a lot of spintronics research, spin electromotive force of FeNi magnetic wire has been reported. However, it is very small. In order to improve it, spin electromotive force of the Rare Earth Transition Metal (RE-TM) which has a large spin orbital interaction has been evaluated. As a result, the electromotive force of the RE-TM magnetic wire is 45 times larger signal compared to that of the FeNi magnetic wire. On the other hand, the RE-TM magnetic wire is covered with Pt thin layer to prevent from oxidation. Recently, it has been found that spin orbital torque effect due to the Pt layer is very large and effective to the magnetic domain wall motion. Therefore, we have studied the spin orbitoronics effect to the domain wall motion of the RE-TM magnetic wire. By using these result, more larger spin electromotive force of the RE-TM magnetic wire would be realized in near future.
