论文摘要
我们通过用于将来的自旋力学应用的电气非本地4末端测量通过悬浮的CU通道进行旋转传输。观察到由于旋转转运而引起的磁化值，其幅度与常规固定Cu侧旋转阀相当。悬浮CU通道中的自旋扩散长度估计在室温下从旋转信号依赖于铁电磁喷油器和检测器电极之间距离的距离为340 nm。发现此值比固定的Cu稍短。悬浮CU通道中自旋扩散长度的减小归因于自旋散射的增加，该旋转散射来自CU通道底部的自然氧化Cu。
We study spin transport through a suspended Cu channel by an electrical non-local 4-terminal measurement for future spin mechanics applications. A magnetoresistance due to spin transport through the suspended Cu channel is observed, and its magnitude is comparable to that of a conventional fixed Cu lateral spin valve. The spin diffusion length in the suspended Cu channel is estimated to be 340 nm at room temperature from the spin signal dependence on the distance between the ferromagnetic injector and detector electrodes. This value is found to be slightly shorter than in a fixed Cu. The decrease in the spin diffusion length in the suspended Cu channel is attributed to an increase in spin scattering originating from naturally oxidized Cu at the bottom of the Cu channel.
