    • As field pulses have a small amplitude (∼2 Oe) and a short pulse length (rise time of 65 ps, fall time of 100 ps, and a duration of 200 ps at half maximum), the excursion of free layer magnetization out of equilibrium will be small. At these conditions the solution to the Landau-Lifshitz-Gilbert equation is an exponential damped sinusoid (see, for instance, for more details). 10.1007/3-540-40907-6-1
