摘要：

We report DEMETER observations of strongly intensified electric noise at the lower hybrid frequency in the midlatitude ionosphere during the recovery phase of a magnetic storm. The spectrum of the noise is broadband and centered at the lower hybrid frequency, which is of a very unusual shape that suggests nonlinear interaction triggered by the injection of ring current ions into the ionosphere.
