The precise sequence changes drastically depending on the magnetization $m_z$ and on the quadratic Zeeman energy $q$ (QZE) in an applied magnetic field. For large QZE, the overall structure of the phase diagram is the same as for an ideal spin 1 gas, although the precise locations of the phase boundaries are significantly shifted by interactions. For small QZE, antiferromagnetic interactions qualitatively change the phase di","authors_text":"A. Invernizzi, C. Frapolli, F. Gerbier, J. Dalibard, K. Jim\\'enez-Garc\\'ia, T.
