Box 45195-313, Zanjan, Iran Journal Article 2016 12 03 In the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. We have also investigated the structure of neutron stars. According to our results, the spin asymmetry stiens the equation of state and leads to high mass for the neutron star. https://ijaa.du.ac.ir/article_60_96c170028a307ed4dcfbe959e754ff15.pdf
