论文摘要
在没有外部磁场和自旋偏振电荷电流的情况下，抗铁磁系统支持两种退化的镁模式。施加的热偏置会激活磁化动力学，从而导致从热边缘到冷边缘的镁流动（镁旋转Seebeck电流）。两个简并带有助于镁电流，但是在不同的带中，镁基础磁矩的方向相反。因此，虽然磁通电流为非零，但净旋转电流为零。
In the absence of an external magnetic field and a spin-polarized charge current, an antiferromagnetic system supports two degenerate magnon modes. An applied thermal bias activates the magnetic dynamics, leading to a magnon flow from the hot to the cold edge (magnonic spin Seebeck current). Both degenerate bands contribute to the magnon current but the orientations of the magnetic moments underlying the magnons are opposite in different bands. Therefore, while the magnon current is nonzero, the net spin current is zero.
