Abstract
Using the solution of the near-neighbor hopping Hubbard model in one dimension by Leib and Wu, it is shown that in the limit of interaction energy much greater than hopping energy, this system has the temperature dependence of magnetization of a free-spin system even for temperatures much less than the bandwidth, for nearly all occupancies of the band.Keywords
