N2 - The ground state magnetism of ferromagnetic spinor Bose-Einstein condensates confined in deep optical lattices was investigated. The 'minicondensates' at each lattice site interacted with neighboring sites through both the static magnetic dipolar interaction and the light-induced dipolar interaction. The 'minicondensates,' behaving as mesoscopic spin magnets, were found to undergo a ferromagnetic or antiferromagnetic phase transition under the magnetic dipolar interaction depending on the dimension of the confining optical lattice.
