Abstract
We investigate the appearance of magnetism in the Hubbard model. In the limit of large value of the interaction , we show that localized moments appear below a critical temperature . We find a Ruderman-Kittel interaction between these moments, which gives an ordered magnetic phase at a critical temperature smaller than .
