  Preliminary results on the properties of transition-metal (Ti, V, Cr, Mn, Fe,
Co, Ni) $\delta$-doped ZnO are reported. Using \emph{ab-initio} electronic
structure calculations the magnetic order is studied assuming both the cubic
rock-salt and zinc-blende structures for ZnO. The ground state magnetic order
is found to depend strongly on the transition-metal atom.
