论文摘要
实验已经确定，旋转玻璃可以支持稳态旋转电流$ \ vec {j} _ {i} $。但是，自旋玻璃动力学的公认理论允许振荡，但没有稳态自旋电流。 Onsager的不可逆热力学意味着自旋电流与磁化的梯度成正比。但是，我们认为与本地平衡磁化$ \ vec {m} $关联的镁分布函数无法分散，因为它代表$ 10^{23} $变量。因此，我们调用非平衡磁化$ \ vec {m} $，在Spintronics中被称为{\ it spin akemulation}。应用不可逆的热力学理论，我们确实发现它可以预测自旋扩散，我们考虑了该理论的其他实验后果，包括反应性和自由度扩散程度之间的波长依赖性耦合。
Experiment has established that spin-glasses can support a steady-state spin current $\vec{j}_{i}$. However, the accepted theory of spin glass dynamics permits oscillations but no steady-state spin current. Onsager's irreversible thermodynamics implies that the spin current is proportional to the gradient of a magnetization. We argue, however, that the magnon distribution function associated with the local equilibrium magnetization $\vec{M}$ cannot diffuse because it represents $10^{23}$ variables. We therefore invoke the non-equilibrium magnetization $\vec{m}$, which in spintronics is called the {\it spin accumulation}. Applying the theory of irreversible thermodynamics we indeed find that it predicts spin diffusion, and we consider other experimental consequences of the theory, including a wavelength-dependent coupling between the reactive and the diffusive degrees of freedom.
