我们在这里从理论和实验上表明,一个Rashba分裂的电子状态内的铁磁体可以有效地转换成一个动态的自旋积累电压。这种效应被理解为源于Rashba分裂,但具有与磁化方向相关的对称性。它是实验测量的自旋泵在astructure中,它被发现是有效的逆自旋霍尔效应在发挥作用时,Pt取代MgO,与额外的优势,不影响在铁磁体的磁阻尼。
We show here theoretically and experimentally that a Rashba-split electron state inside a ferromagnet can efficiently convert a dynamical spin accumulation into an electrical voltage. The effect is understood to stem from the Rashba splitting but with a symmetry linked to the magnetization direction. It is experimentally measured by spin pumping in astructure where it is found to be as efficient as the inverse spin Hall effect at play when Pt replaces MgO, with the extra advantage of not affecting the magnetic damping in the ferromagnet.
