论文摘要
我们提出了在低温温度下的铁磁纳米线中自旋seebeck效应（SSE）的非线性理论。我们基于两级系统的集合采用微观量子噪声模型。在电线的PT探测器的某些位置，横向SSE随温度和/或温度梯度的函数而变化。另一方面，纵向SSE甚至没有远远超出线性响应理论的有效性状态，也没有显示出明显的非线性。
We present a theory of the non-linearities of the spin Seebeck effect (SSE) in a ferromagnetic nanowire at cryogenic temperatures. We adopt a microscopic quantum noise model based on a collection of two-level systems. At certain positions of Pt detectors to the wire, the transverse SSE changes sign as a function of temperature and/or temperature gradient. On the other hand, the longitudinal SSE does not show significant non-linearities even far outside the regime of validity of linear response theory.
