Extended Data Fig. 4: Static longitudinal MOKE measurement of Mn3Sn and Co.
From: Spin-torque-driven gigahertz magnetization dynamics in the non-collinear antiferromagnet Mn3Sn
a, Static longitudinal MOKE measurement setup with a lens. The laser is incident parallel to the x-axis but offset by 2 mm from the center of the lens. Then, the laser is focused on the sample with a fixed oblique angle of 20°, determined by the numerical aperture of the lens. b, Static Kerr rotation of Pt/Mn3Sn samples according to the external magnetic field. c,d Static Kerr rotation of c Mn3Sn and d Co as a function of thickness. Data points of c,d are represented as mean value ± standard deviation of the five times repeated measurements.
