It is shown that charged dust particles carrying a considerable proportion of the negative charge of a structured magnetized plasma can lead to low‐frequency electromagnetic surface waves which otherwise do not exist. The waves are Alfvén‐like and propagate across the stationary external magnetic field with a frequency below the ion cyclotron but much above the dust cyclotron frequency. The dispersion characteristics of the modes are obtained and applications to space plasmas discussed.
