FERROMAGNETIC PHASE TRANSITIONS IN THE HUBBARD MODEL
M. D. Coutinho-FilhoDepartamento de Fisica, Universidade Federal de Pernambuco 50739, Recife, Brazil
Abstract
We show that the coupling of charge and spin density fluctuations in the three-dimensional Hubbard model with total charge fixed severely restricts the occurrence of a continuous ferromagnetic transition.
