This thesis studies magnetic switching of a Stoner-Wholfarth particle. The particle is characterized by a uniaxial magnetic anisotropy, and the magnetic field driving the switching is applied along the anisotropy axis. In addition, a constant small bias field is applied perpendicular to the easy axis. The dynamics of the magnetic moment are studied numerically by solving the Landau-Lifshitz-Gilbert (LLG) equation. Numeric results obtained without any approximations are then compared to the analytic theory of switching time in a perpendicular bias field. A good correspondence between the approximate analytic and exact numeric values of the switching time is observed in a wide parameter region.
