摘要：

We present results of the exact diagonalization of fcc Hubbard clusters by increasing the primitive tetrahedral cell and obeying the fcc lattice symmetries. Ground state properties such as the energy spectrum, the total spin of the cluster and spin pairing correlation functions have been calculated and a magnetic phase diagram is reported.
