  • Abstract
    We have developed a new method for the computation of switching rates in magnetic systems. It can be shown to give the same results as brute-force Landau-Lifshitz-Gilbert (LLG) simulation, but much faster because it does not waste time simulating low-energy precessional trajectories, but concentrates on switching and near-switching trajectories. We show how the method can be applied to the calculation of thermal switching rates that are many orders of magnitude slower than precessional rates
