  Spin-spin correlation function response in the low electronic density regime
and externally applied electric field is evaluated for 2D metallic crystals
under Rashba-type coupling, fixed number of particles and two-fold energy band
structure. Intrinsic Zeeman-like effect on electron spin polarization, density
of states, Fermi surface topology and transverse magnetic susceptibility are
analyzed in the zero temperature limit. A possible magnetic state for Dirac
electrons depending on the zero field band gap magnitude under this conditions
is found.
