Stochastic Dynamics of Magnetic Nanoparticles at Finite Temperatures

Abstract:

We consider unstable motion in small magnetic particles, driven by an external magnetic field and influenced by thermal fluctuations. Our studies demonstrate both temporal and spatial complexity of the dynamics in this system. The results are obtained using numerical simulations of the Landau-Lifshitz-Gilbert equations.
