概要	The spontaneous spin polarization of strongly interacting matter due to axial-vector and tensor type interactions is studied at zero temperature and high baryon-number densities. We start with the mean-field Lagrangian for the axial-vector and tensor interaction channels, and find in the chiral limit that the spin polarization due to the tensor mean field (U) takes place first as the density increases for sufficiently strong coupling constants, and then that due to the axial-vector mean field (A) emerges in the region of finite tensor mean field. The mechanism for this result is presented in relation to theaxialU(1) symmetry breaking.
