Spin and charge conversion in non-collinear antiferromagnets. a Crystalline and magnetic structures of Mn3Sn in the ab plane. b Large anomalous Hall effect in Mn3Sn arising from the non-collinear antiferromagnetic order (\(\rho _H^{AF}\)) at room temperature. c Illustration of the spin Hall effect arising from the non-collinear 120-degree spin order. d Facet-dependent large spin Hall effect in antiferromagnet IrMn3. Olive, blue, and cyan circles indicate (001)-oriented, (111)-oriented, and polycrystalline IrMn3 thin films. The effective spin Hall angles are obtained by measuring the spin orbit torque in IrMn3/Py bilayer devices via ST-FMR technique.
