论文摘要
电旋转生成是推动旋转基质领域的核心现象之一。使用{\ em ab intib}计算，我们表明，室温金属界线抗铁磁性抗ruo $ _2 $允许高效的自旋产生，这是由沿NéelVectorAxis沿着旋转和向下旋转的各向异性切割带引起的。零净力矩抗铁磁铁充当电旋转分机，在旋转和旋转电流之间具有34 $^\ circ $繁殖角。相应地，自旋传导性比对20,000个非磁性自旋式材料的调查的记录值大三倍。我们提出了一种使用反铁磁性Ruo $ _2 $胶片与Ferromagnet连接的多功能旋转式刺激概念。
Electrical spin-current generation is among the core phenomena driving the field of spintronics. Using {\em ab initio} calculations we show that a room-temperature metallic collinear antiferromagnet RuO$_2$ allows for highly efficient spin-current generation, arising from anisotropically-split bands with conserved up and down spins along the Néel vector axis. The zero net moment antiferromagnet acts as an electrical spin-splitter with a 34$^\circ$ propagation angle between spin-up and spin-down currents. Correspondingly, the spin-conductivity is a factor of three larger than the record value from a survey of 20,000 non-magnetic spin-Hall materials. We propose a versatile spin-splitter-torque concept utilizing antiferromagnetic RuO$_2$ films interfaced with a ferromagnet.
