In this letter, we present a numerical model of magnetization dynamics that is based on the classical Stoner–Wohlfarth model and the Landau–Lifshitz–Gilbert equation. This approach uses a series of coefficients for the interpolation of the time needed by the magnetic moment to reach equilibrium and a linear system of equations for the variation in time of the angular components of the magnetization. The dynamic Stoner–Wohlfarth model will be used to accurately replicate the dynamic behavior of macrospins with significantly improved numerical efficiency when a constant or variable external magnetic field is applied.
