The understanding of electron behaviour in systems with reduced dimensionality and lengthscale is a central theme of contemporary condensed matter physics. Nanomagnetic systems allow us to rigorously test our understanding of such phenomena with the additional benefit that many of the observed properties have direct technological relevance. Much of the interesting physics and functionality resides within nanometres of the interface. Providing an atomic understanding of such phenomena presents a significant experimental challenge. The interfaces of interest are often buried and not readily accessible to more conventional techniques. Neutron and resonant x-ray scattering complemented with magnetic dichroism techniques are ideally suited to the study of such systems. We shall demonstrate the interface/surface sensitivity in a system exhibiting a magnetostructural phase transition and one in which there exists a magnetic reconstruction at the surface of an antiferromagnet. The wider implications for the control of interfacial magnetism will also be discussed.
