Abstract: Whether a spin-1-2 Fermi gas will become ferromagnetic as the strength ofrepulsive interaction increases is a long-standing controversial issue.Recently this problem is studied experimentally by Jo et al, Science, 325, 15212009 in which the authors claim a ferromagnetic transition is observed. Thiswork is to point out the results of this experiment can not distinguish whetherthe system is in a ferromagnetic state or in a non-magnetic but stronglyshort-range correlated state. A conclusive experimental demonstration offerromagnetism relies on the observation of ferromagnetic domains.
