We investigate the possibility of an unconventional spin density wave (SDW) in the attractive Hubbard model with finite spin polarization. We show that pairing and density fluctuations induce a transverse d-wave SDW near the half-filling. This novel SDW is related to the d-wave superfluidity induced by antiferromagnetic spin fluctuations, in the sense that they are connected with each other through Shibas attraction-repulsion transformation. Our results predict the d-wave SDW in real systems, such as cold Fermi atom gases with a population imbalance and compounds involving valence skipper elements.
