We propose the use of mechanical strain and mild annealing to achieve reversible modulation of spin-orbit torque (SOT) and Gilbert damping parameter. X-ray diffraction results show that the residual spin-orbit torque enhancement and Gilbert damping reduction, due to the post-mechanical strain treatm...
