Notes:
A dynamic generalization of the Stoner–Wohlfarth (SW) model is presented, in which the applied field component haz parallel to the particle anisotropy axis is slowly varied, whereas the one in the perpendicular plane, ha⊥, is rotated at the angular frequency ω. The Landau–Lifshitz–Gilbert equation is solved to calculate the system response under the constraint of spatially uniform magnetization at all times. Switching under slowly varying haz is discussed. Various switching modes can occur in correspondence of different types of bifurcation present in the dynamics. In addition, it is shown that the system response can become quasiperiodic, with spontaneous magnetization oscillations at a frequency definitely lower than ω. © 2001 American Institute of Physics.
