TR-MOKE-measured ultrafast magnetization dynamical signal in CoFeB/MgO/CoFeB film at parallel and antiparallel states. (a) Measurement signal. (b) Normalized curves of TR-MOKE signals (normalized at 2 ps). Full and empty circular dots present the parallel state (P) and the antiparallel state (AP), respectively. The solid lines are fits to the experimental data.^{[ 81 ]}
