We have studied the local magnetization dynamics in exchange-biased magnetic tunnel junction (MTJ) elements, by time-resolved magneto-optical Kerr effect measurements. We have observed a strong spatial dependence of the frequency and damping of the precessional motion in the free layer. A local edge
