Electrical spin-current generation is among the core phenomena driving the eld of spintronics. Using ab initio calculations we show that a room-temperature metallic collinear antiferromagnet RuO2 allows for highly efficient spin-current generation, arising from anisotropically-split bands with conserved up and down spins along the Neel vector axis.
