Abstract

It is shown that Alfvén waves propagating parallel and antiparallel to a magnetic field can be generated and amplified in an acoustically active heat-releasing ionized medium. The amplification is due to parametric energy pumping from the unstable magnetoacoustic waves to the Alfvén waves.
