Time evolutions of the total magnetization in the Ni layer from its initial value, both for parallel and antiparallel configurations (ɛ=0.1) The dashed line presents the approximate result from Eq. (10). Note that here and henceforth in corresponding figures the value of the function MNi(t) at t=0 is chosen as zero, i.e., only the essential remagnetization dynamics is shown.
