摘要: We study the deterministic spin dynamics of an anisotropic magnetic particle in presence a field with constant longitudinal and time-dependent transverse component using Landau-Lifshitz-Gilbert equation. characterize dynamical behavior system through calculation Lyapunov exponents, Poincar\'e sections, bifurcation diagrams, Fourier power spectra. In particular we explore positivity largest exponent as function magnitude frequency applied its direction respect to main anisotropy axis particle. find that presents multiple transitions between regular chaotic behaviors. show phases display very complicated structure intricately intermingled phases.
