It is shown that the nonlinear interaction of large amplitude electrostatic ion-cyclotron oscillations with low-frequency perturbations causes a modulational instability. The most important cases of adiabatic density perturbations and low-frequency changes in the magnetic field strength are considered. The nonlinear equation which governs the asymptotic state of the modulationally unstable ion-cyclotron mode admits a soliton or soliton-like solution for the electric potential.
