论文摘要

从理论上讲,我们证明了抗铁磁体中的超快磁性动力学与其铁磁对应物相比具有交换增强。我们为使用原子旋转动力学方法验证的磁性动力学提供了运动方程。在转子之间的角动量的交换加快了抗铁磁体的动力学,这是铁磁体中缺少的过程。

We theoretically demonstrate that the ultrafast magnetic order dynamics in antiferromagnets is exchange-enhanced in comparison to their ferromagnetic counterparts. We provide an equation of motion for the magnetic order dynamics validated by computer simulations using atomistic spin dynamics methods. The exchange of angular momentum between sublattices speeds up the dynamics in antiferromagnets, a process absent in ferromagnets.
