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