Abstract	In the past, nuclear magnetic resonance (NMR) studies have proved useful for structural investigations of magnetic multilayers in the direct space and at the atomic scale, complementing standard structural investigations [1]. Actually NMR provides with an original insight into the structural and magnetic characterization of composite nanostructured materials. Indeed the yield of NMR experiments is twofold. On one hand, the NMR spectrum, usually acquired in zero external field, reflects the distribution of hyperfine fields in the sample, and thus gives information about the different chemical configurations and site symmetries in the sample, the different phases, their structure, and their defects. On the other hand, the evolution of the spectral shape against the external field strength and orientation or against the radio frequency field strength probes the magnetic anisotropy or the magnetic stiffness of the electronic moments around the nucleus site, thus providing an information comparable to that given by ferromagnetic resonance (FMR) measurements. Therefore, combining both yields makes it possible to correlate the inhomogeneous magnetic properties of a composite sample to its different structural components [2]. The structural aspects of NMR studies are summarized in the first part of the chapter. Most of the chapter is devoted, though, to the analysis of NMR data in terms of local magnetic properties.
