摘要: Abstract The Landau–Lifshitz–Gilbert equation is analyzed in the case of a configuration involving easy plane isotropy under influence sinusoidally oscillating magnetic field and demagnetizing field. Through use numerical techniques, chaotic behavior found analyzed. By reducing system to discrete map (numerically), bifurcation diagrams for are computed. exhibit period doubling cascade route chaos, it obeys certain convergence rules transitions outlined by Feigenbaum. A connection drawn between chaos geometry system, comparisons made with similar systems. Within regime, windows arbitrarily large suspected exist, explicitly illustrated discussed three window.
