Abstract: We investigate magnetic phase in the bilayer system of ultra-cold bosons in an optical lattice, which is involved with Raman-induced spin-orbit (SO) coupling and laser-assisted interlayer tunneling. It is shown that there exit a rich of spin textures such as hetero-ferromagnet, chiral ferromagnet, and chiral antiferromagnet. In particular, hetero chiral ferromagnet induced by SO coupling exists extremely rarely in real materials. We present detailed experimental setup of realizing such model in cold atom system.
