发展了一种不同类型的侧向自旋阀结构，该结构由一对紧密排列在均匀铜膜上的坡莫合金纳米柱组成。从自旋信号的偏置电流和温度依赖关系来看，纳米级横向自旋阀与传统的横向自旋阀相比，在产生纯自旋流方面具有几个优点。我们还表明，增加自旋注入器的数目可以提高产生自旋流的限制。(C)2012年美国物理研究所。[http://dx.doi.org/10.1063/1.3698092]
A different type lateral spin valve structure consisting of a pair of the closely located Permalloy nanopillars on a uniform copper film has been developed. From the bias-current and temperature dependences of the spin signal, the nanopillar lateral spin valve was found to have several advantages for generating the pure spin current over the conventional lateral spin valves. We also show that the limitation of the generating spin current can be enhanced by increasing the number of the spin injectors. (C) 2012 American Institute of Physics.
