Nuclear spins in silver constitute an ideal antiferromagnetic spin-1/ 2 model system in an fee lattice. The nuclei are well localized and the interactions coupling the spins can be calculated from first principles. Strong quantum effects are expected owing to spin-1/2. The magnetic phase diagram of the system has been investigated by several theoretical methods In the present study the feasibility of neutron diffraction experiments on nuclear magnetic order in silver is discussed. The requirements for cryogenics and for neutron equipment are based on experience with current NMR measurements on silver and with neutron diffraction work on copper. It is concluded that an experiment using an isotopically enriched specimen of either 107Ag or 109Ag is feasible but difficult.
