Temperature effects on the nonstationary Karpman–Washimi ponderomotive magnetization in quantum plasmas

The temperature effects on the nonstationary Karpman–Washimi ponderomotive magnetization are investigated in quantum Fermi plasmas. The cyclotron frequency due to the ponderomotive force of the electromagnetic wave has been obtained as a function of the Fermi Debye length and quantum wavelength. It is found that the Karpman–Washimi ponderomotive magnetization decreases with increasing Fermi temperature. The maximum position of the Fermi Debye length is found to be increased with an increase in the frequency in the small Fermi Debye length domain. It is also shown that the Fermi ponderomotive magnetization decreases with increasing frequency in the large Fermi Debye length domain. In addition, it is shown that the frequency dependence on the ponderomotive magnetization diminishes with increasing Fermi temperature.
