  We present magnetic properties of the three-band Hubbard model in the para-
and antiferromagnetic phase on a hypercubic lattice calculated with the
Dynamical Mean-Field Theory (DMFT). To allow for solutions with broken
spin-symmetry we extended the approach to lattices with AB-like structure.
Above a critical sublattice magnetization m_d=0.5 one can observe rich
structures in the spectral-functions similar to the t-J model which can be
related to the well known bound states for one hole in the Neel-background. In
addition to the one-particle properties we discuss the static
spin-susceptiblity in the paramagnetic state at the points q=0 and
q=(pi,pi,pi,...) for different dopings delta. The delta-T-phase-diagram
exhibits an enhanced stability of the antiferromagnetic state for
electron-doped systems in comparison to hole-doped. This asymmetry in the phase
diagram is in qualitative agreement with experiments for high-T_c materials.
