@article{Hashimoto2019SpinBA, title={Spin backflow: A non-Markovian effect on spin pumping}, author={Kazunari Hashimoto and Gen Tatara and Chikako Uchiyama}, journal={Physical Review B}, year={2019} }

The miniaturization of spintronic devices, specifically, nanoscale devices employing spintronics, has attracted intensive attention from a scientific as well as engineering perspective. In this paper, we study a non-Markovian effect on spin pumping to describe spin current generation driven by the magnetization of arbitrary precession frequency in a quantum dot attached to an electron lead. Although the Markovian approximation can be used when driving is sufficiently slow compared with… Expand
