Since their discovery, topological insulators have been expected to be idealspintronic materials owing to the spin currents carried by surface states withspin--momentum locking. However, the bulk doping problem remains an obstaclethat hinders such application. In this work, we predict that a newly discoveredfamily of topological materials, the Weyl semimetals, exhibits large intrinsicspin Hall effects that can be utilized to generate and detect spin currents.Our $ab~initio$ calculations reveal a large spin Hall conductivity that iscomparable to that of $4d$ and $5d$ transition metals. The spin Hall effectoriginates intrinsically from the bulk band structure of Weyl semimetals, whichexhibit a large Berry curvature and spin--orbit coupling, so the bulk carrierproblem in the topological insulators is naturally avoided. Our work not onlypaves the way for employing Weyl semimetals in spintronics, but also proposes anew guideline for searching for the spin Hall effect in various topologicalmaterials.
