a) Time trace of the Kerr rotation measured for maximum pump fluence, such that the step due to spin reorientation transition was saturated. b) Illustration of the spin reorientation responsible for the step in panel a). This step can be attributed to the rotation of the magnetization from the x-axis (in plane) to the z-axis (out of plane). We approximate the deflection angle with the ratio of the oscillation amplitude and the step and find that this angle is approximately 15 degrees. We note that the direction of the spin reorientation is determined by the polarization of the pump pulse, as has been previously reported in ref. 53.
