With the continued demand for ever smaller and faster magnetic sensors based on thin-film technology the requirements for deeper understanding of the relevant processes involved continue to grow. Simple modeling methods based on Maxwell's equations, and simple experimental techniques that measure only bulk magnetic properties, served the industry well for the latter part of the twentieth century but are no longer adequate research tools for the engineering of the nanometer magnetic devices of today and tomorrow. This talk will review some of the detailed knowledge of both static and time-dependent behavior of interacting magnetic grains within films and multilayers that can be gained through micromagnetic simulations based on the Landau-Lifshitz-Gilbert (LLG) equations. Opportunities for the use of a variety neutron scattering techniques to measure such detailed equilibrium and dynamic properties will be discussed.
