Quasi-Alfven waves, their self-excitation and spontaneous radiation
L. E.Gurevich L. E., Zegrya G. G.
New type of low-frequency waves, which we call thermodynamic quasi-Alfven waves, can be self-excited in metals in which the electron and hole densities are the same, if a temperature gradient and a magnetic field parallel to it both exist. The frequency of these waves is proportional to the temperature gradient. Under conditions that can easily be achieved in the experiment, these waves are self-excited and a spontaneous rf radiation is emitted from the metal in which this occurs.
