  The properties of spin polarized pure neutron matter and symmetric nuclear
matter are studied using the finite range simple effective interaction, upon
its parametrization revisited. Out of the total twelve parameters involved, we
now determine ten of them from nuclear matter, against the nine parameters in
our earlier calculation, as required in order to have predictions in both spin
polarized nuclear matter and finite nuclei in unique manner being free from
uncertainty found using the earlier parametrization. The information on the
effective mass splitting in polarized neutron matter of the microscopic
calculations is used to constrain the one more parameter, that was earlier
determined from finite nucleus, and in doing so the quality of the description
of finite nuclei is not compromised. The interaction with the new set of
parameters is used to study the possibilities of ferromagnetic and
antiferromagnetic transitions in completely polarized symmetric nuclear matter.
Emphasis is given to analyze the results analytically, as far as possible, to
elucidate the role of the interaction parameters involved in the predictions.
