| Abstract | We observed an oscillatory behavior, both in space and time, of the induction in Bi2Sr2CaCu2O8 crystals exposed to a steady magnetic field. This new ‘‘flux waves’’ phenomenon appears near the orderdisorder vortex phase transition, under specific conditions of temperature and induction gradient. A theoretical description of this effect is based on two coupled equations: the Landau-Khalatnikov dynamic equation for the order parameter of the vortex phase transition and the diffusion equation for the time evolution of the magnetic induction. A linear stability analysis of these equations predicts an oscillatory instability characterized by a period and wavelength in accordance with the experimental results. |
