本文将双带自旋扩散模型推广到非平衡系统，研究了铁磁金属中最近发现的自旋-塞贝克效应。使用该模型的计算很好地再现了Ni 81 Fe 19膜的实验结果;电化学电势的梯度是不同的上下自旋带之间的温度差的影响的膜的两端之间。
The two-band spin diffusion model has been extended to nonequilibrium systems to investigate the recently discovered spin-Seebeck effect in a ferromagnetic metal. A calculation using this model well reproduces the experimental results for a Ni81Fe19 film; the gradient of electrochemical potential is different between up- and down-spin bands affected by a temperature difference between the ends of the film.
