摘要: Effect of demagnetization field on chaotic and deterministic nonlinear magnetization dynamics regimes formation in the presence oscillating constant external magnetic fields is studied using Landau–Lifshitz–Gilbert approach. The uniformly magnetized sample considered to be an axially symmetric particle described by factors have uniaxial crystallographic anisotropy formed some angle with applied direction. equations moment motion are synergetic system behavior examined phase plane. It investigated as how change shape its orientation respect (system’s configuration) can cause transition between chaos regular dynamics. Moreover, way completely suppress moments such proposed. To produce a study, all results presented form bifurcation diagrams for suffic...
