超导性提供了一个巨大的增强自旋电池效应
Superconductivity provides a giant enhancement to the spin battery effect
摘要：
我们发展了一个考虑磁邻近效应的超导体/铁磁绝缘体（SC/FI）系统的自旋电池效应理论。我们表明，自旋能量混合启用的超导性导致增强自旋积累的几个数量级相对于正常状态。这一发现可以解释最近观察到的SC/FI系统中热磁振子产生的巨逆自旋霍尔效应。我们提出了一种非局域的电学探测方案，可以直接探测由磁化动力学驱动的自旋积累。我们预测了一个巨大的塞贝克效应转换成非本地电压信号的磁振子温度偏置。我们还展示了如何可以用来提高磁振子检测的灵敏度，甚至到单磁振子水平。
英文摘要：
We develop a theory of the spin battery effect in superconductor/ferromagnetic insulator (SC/FI) systems taking into account the magnetic proximity effect. We demonstrate that the spin-energy mixing enabled by the superconductivity leads to the enhancement of spin accumulation by several orders of magnitude relative to the normal state. This finding can explain the recently observed giant inverse spin Hall effect generated by thermal magnons in the SC/FI system. We suggest a non-local electrical detection scheme which can directly probe the spin accumulation driven by the magnetization dynamics. We predict a giant Seebeck effect converting the magnon temperature bias into the non-local voltage signal. We also show how this can be used to enhance the sensitivity of magnon detection even up to the single-magnon level.
