摘要: Using the finite-temperature Landau–Lifshitz–Gilbert equation we investigate magnetization dynamics and its control of a monodomain ferromagnetic nanoparticle subjected to short magnetic-field pulses. In particular clarify role magnetic field orientation provide analytical numerical results indicating optimum tilting achieve faster, low-field switching.
