The magnetic structure at the ground state of the single band Hubbard modelis investigated. The extended Gutzwiller method is adopted. It is found, if theintra-atomic Coulomb integral is sufficiently large, that the ferromagnetic orantiferromagnetic ground states are obtained at nearly half-filled band in thecases of the simple cubic and body centered cubic structures and that the fer-romagnetic ground states are obtained at more than half-filled band in the casesof the face centered cubic and hexagonal closed packed structures.
