Abstract
Low-frequency electromagnetic plasma excitations in the presence of an extra specie, are investigated. The stationary spectra of the low-frequency electromagnetic excitations and the relevant transport coefficients are found. It is conjectured that intrusion of an adiabatically distributed component decreases the level and additional nonlinear broadening of the convective spectrum. The anomalous electron heat conductivity associated with the short-wave motions, is reduced due to the presence of a third specie. The dope also affects anomalous diffusion relevant to the long-wave perturbations in the plasma periphery.
