Can spinor dipolar effects be observed in Bose-Einstein condensates?

Weak dipolar effects in atomic Bose-Einstein condensates (BECs) have recently been predicted to develop spin textures. However, observation of the spin textures requires us to decrease the magnetic field down to similar to 10 mu G for spin-1 alkali BECs, so that they are not washed out by the Zeeman effect. We present a scheme to observe the magnetic dipole-dipole interaction in alkali BECs under a realistic magnetic field of similar to 100 mG. Our scheme enables us to extract genuine dipolar effects and should apply also to Cr-52 BECs.
