We present a theory for the oscillating instability of the vortex matter experimentally observed in Bi2Sr2CaCu2O crystals. The basic framework is a flux dynamics instability in the vicinity of the coexistence line of the order-disorder vortex phase transition. A theoretical description of this effect is based on two coupled equations: the Landau-Ginzburg equation for the order parameter of the vortex phase transition and the diffusion equation for the magnetic induction. Linear stability analysis of these equations reveals an oscillatory instability giving rise to waves and characterized by a period and wavelength that are in accordance with the experimental results.
