Future science at next generation neutron sources

We review some of the scientific opportunities which will become available with the advent of increased fluxes of polarized neutrons and corresponding advances in neutron instrumentation. These range from the study of magnetism in thin films and novel nanostructures with application in magnetic information storage and retrieval, to the study of spin-dependent inelastic scattering from highly correlated magnetic systems, frustrated magnetic systems, etc. Extensions of neutron spin echo techniques offer further opportunities for advances in our knowledge of the dynamics of soft condensed matter systems.
