摘要: The dynamics of an individual magnetic moment is studied through the Landau-Lifshitz equation with a periodic driving in direction perpendicular to applied field. For fields lower than anisotropy field and small values perturbation amplitude we have observed bistability. At intermediate found quasiperiodic bands alternating motion. even larger chaotic regime found. When one, behavior regions. Those appear periodically oscillating Also, for low force, not parallel
