Spin Hall effect (SHE) is a convenient phenomenon which converts electric currents into spin currents. SHE is considered an effective spin current source and is often used in combination with magnetic materials to manipulate their spins. Recently, it has been shown that SHE in chiral antiferromagnet DO₁₉-Mn₃Sn has different characteristics from that in typical non-magnetic spin Hall materials, such as Pt and Ta, which originates from the chiral magnetic structure in conjunction with the non-zero anomalous Hall effect. In this work, we fabricated antiferromagnetic L1₂-Mn₃Ir thin films having a chiral magnetic structure and investigated the spin transport properties as well as the spin Hall effect.
