Abstract

As shown within the gyrokinetic framework, drift-compressional waves can propagate in the magnetosphere in the direction of energetic electron drift. The plasma is assumed to be composed of cold particles with an admixture of hot protons with a Maxwell distribution and electrons with an inverted distribution. The conditions of existence of such waves and their intensification due to resonance interaction with energetic electrons (drift instability) have been de- termined. The results can be helpful in interpreting observation of wave phenomena in the magnetosphere with frequencies in the range of geomagnetic pulsations Pc5 and below.
