摘要：

For an infinite ferromagnetic cylinder with exchange, uniaxial anisotropy, demagnetizing field, and an external magnetic field applied along its axis curling-mode solutions to Brown's equation (the static Landau-Lifshitz equation) exist. It is proved that these solutions are unstable, and by analogy to a specific-sized water droplet in a supersaturated vapor for which an unstable equilibrium exists, the solution for a given magnetic field is shown to be the configuration of smallest energy through which magnetization reversal can nucleate in the curling mode.
