In this work, we study the spin-orbit torque (SOT) switching properties of the Mn3Sn depending on the annealing condition. The Mn3Sn thin films were prepared on MgO (110) substrates with different annealing conditions using an UHV magnetron sputtering system. We found that the annealing process gives rise to tensile strain in the ( direction in the Mn3Sn layer. The strain also enhances SOT-induced switching property of the Mn3Sn film. Our work provides further scientific and technological advances in antiferromagnetic spintronics based on Mn3Sn.
