  In this paper, we investigate the liquid gas phase transition for the spin
polarized nuclear matter. Applying the lowest order constrained variational
(LOCV) method, and using two microscopic potentials, $AV_{18}$ and
$UV_{14}$+TNI, we calculate the free energy, equation of state, order
parameter, entropy, heat capacity and compressibility to derive the critical
properties of spin polarized nuclear matter. Our results indicate that for the
spin polarized nuclear matter, the second order phase transition takes place at
lower temperatures with respect to the unpolarized one. It is also shown that
the critical temperature of our spin polarized nuclear matter with a specific
value of spin polarization parameter is in good agreement with the experimental
result.
