| Description | Journal: Philosophical Magazine The study of magnetism and crystallography of nanostructures is one of the most challenging topics, at present. Novel structures were grown, which do not exist in the bulk; the magnetism of these nano-sized particles and films may differ from the bulk by orders of magnitude. Synergistic applications of theory and experiment in materials science are all important for a fundamental understanding. The most important parameters are the magnetic anisotropy energy (MAE) and the interlayer exchange coupling (IEC) in multilayers. We will discuss examples where ab-initio calculations adapted to existing experiments disentangle the importance of surface and volume effects in the MAE, as well as a layer-resolved IEC and its T-dependence. The Weinberger group has unambiguously shown that the 'volume part' of the MAE is most important to understand the spin reorientation transition (SRT) in Ni/Cu. They also calculated the IEC layer-by-layer in the T = 0 limit for a trilayer. Very recently, in theory, spin wave excitations were added to interpret the experimental findings. |
