We explore the spin-polarization of quark matter in the NJL model including the scalar and tensor interactions. There are two kinds of spin-polarized phases: one appears in the chiral-broken phase where the quark mass is non-zero, and the other in the chiral-restored phase where the quark mass is zero.
