Abstract:  
By calculating the dielectric permittivity of a magnetoactive plasma discharge in the presence of an external electric field, lowfrequency instabilities resulting from the dependency of the electronneutral collision frequency, electronion recombination coefficient and ionization frequency on the electron temperature are investigated. Furthermore, it is shown that some ofthese instabilities depend on the sign change of the derivative of the kinetic coefficients with respect to the electron temperature. Finally, it is shown how frequency spectra and the development of instabilities are changed by increasing the strength ofthe external magnetic field.
