  The ponderomotive force is involved in a variety of space plasmas phenomena
which are characterized by the family of Kappa distributions. Therefore,
evaluating these nonthermal effects in the ponderomotive force is required. The
Washimi and Karpman ponderomotive interaction due to cyclotron waves is
evaluated for different space conditions considering low-temperature magnetized
plasmas described by an isotropic Kappa distribution and with a wave
propagation parallel to the background magnetic field. We performed a brief
analysis of the influence of the Kappa distribution in the dispersion relation
for a low-temperature plasma expansion at the lowest order in which the thermal
effects are appreciated without considering the damping characteristics of the
wave. The different factors of the ponderomotive force are obtained and
analyzed separately as a function of the wavenumber, the spectral index
$\kappa$, and the plasma beta. We have found a relevant influence of the
non-thermal effects in all the factors of the ponderomotive force for
magnetized plasmas. The effect of the kappa distribution has been evaluated for
a wide variety of space environments as the solar wind and the different
regions of our magnetosphere where it has been found that these results can be
relevant for the solar wind, the magnetosheath, the plasmasheet, and the polar
cusps. We have also analyzed the role of the non-thermal effect in the induced
Washimi and Karpman ponderomotive magnetization in the context of spatial
plasmas and the total power radiated associated with it. We find that even for
nearly cold magnetized plasmas and waves far from the resonances the effect of
the kappa parameter in the ponderomotive force cannot be neglected. This
suggests a significant role of the Kappa distribution in ponderomotive
phenomena of space physics.
