  The dielectric permeability tensor for spin polarized plasmas is derived in
terms of the spin-1/2 quantum kinetic model in six-dimensional phase space.
Expressions for the distribution function and spin distribution function are
derived in linear approximations on the path of dielectric permeability tensor
derivation. The dielectric permeability tensor is derived the spin-polarized
degenerate electron gas. It is also discussed at the finite temperature regime,
where the equilibrium distribution function is presented by the spin-polarized
Fermi-Dirac distribution. Consideration of the spin-polarized equilibrium
states opens possibilities for the kinetic modeling of the thermal spin current
contribution in the plasma dynamics.
