Magnetic materials present a variety of behaviours, for example, weak magnetism vs the localized moment limit. In this seminar, I will discuss the difference between these two limits and present a literature review on computing the magnetic response from first principles. In particular, we focus on the applicability and limitations of the localized-moment picture in comparison with the response obtained with time-dependent density functional theory.
