abstract = {We investigate four CuAu-I-type metallic antiferromagnets
for their potential as spin current detectors using spin
pumping and inverse spin Hall effect. Nontrivial spin Hall
effects were observed for FeMn, PdMn, and IrMn while a much
higher effect was obtained for PtMn. Using
thickness-dependent measurements, we determined the spin
diffusion lengths of these materials to be short, on the
order of 1 nm. The estimated spin Hall angles of the four
materials follow the relationship PtMn>IrMn>PdMn>FeMn,
highlighting the correlation between the spin-orbit coupling
of nonmagnetic species and the magnitude of the spin Hall
effect in their antiferromagnetic alloys. These experiments
are compared with first-principles calculations. Engineering
the properties of the antiferromagnets as well as their
interfaces can pave the way for manipulation of the spin
dependent transport properties in antiferromagnet-based
spintronics.},
