It is very important to know the spins on magnetic atoms embedded in a molecular network. Single or multiple magnetic atoms with a large spin can be used as molecular magnets for magnetic storage devices. We use denisty functional theory (DFT) with pseudopotentials and GGA+U to calculate spin on Ti atoms adsorbed on CuN/Cu(100) surface; and compare this spin with that obtained from scanning tunneling microscopy experiments. Then we calculate the exchange coupling for a complete layer of Ti, as well as dimers of Ti on the same CuN/Cu(100) surface.
