Room temperature free layer switching rate. The rate is mapped as a function of the applied ac voltage Vac and frequency f for a experiment and b numerical solution of the stochastic LL equation (Eq. (1)). The black line overlayed on (b) is analytical prediction of the threshold voltage for the onset of zero-temperature chaotic dynamics due to heteroclinic tangle, while the gray line is experimentally measured threshold voltage obtained from the experimental data in (a)
