LLG simulation of MRAM switching rates

In this paper we describe a new method for computing rates by LLG (Landau-Lifshitz-Gilbert) simulation, and also show that the simple transition state theory (TST) approximation is not only very accurate. The problem of calculating MRAM switching rates has been well-studied for the case of thermal switching in uniaxial particles, mostly by solution of the Fokker-Planck (FP) equation for a non-steady state system.
