✦ Synopsis

The effective Hamiltonians that describe the low-lying energy states of some stacked organometallic ferromagnets with dopants have been derived. It is shown that the lattice stack with N unit cells and p conduction electrons has the ground-state Ž . Ž . spin S s N q p r2 at p -N and S F 3 N y p r2 at N F p -2 N. This means that 0 0 the ferromagnetic ground state of metallocene-based donor᎐acceptor stack is unstable to the donor doping and is stable to the acceptor doping.

We have investigated the precision achievable, with state-of-the-art lithography, in the fabrication of quantum dots for the realization of quantum cellular automaton cells, and we have compared it with the requirements for proper device operation. Our conclusion is that a simple 'hole-array' approa
