Nuclear Magnetic Resonance is very commonly used in chemistry or biology however Its use for studying ferromagnetic materials is much more confidential. The reason is that when performed on ferromagnets, the NMR signal shows specific properties that require the development of dedicated experimental set ups as well as analyses methods. Therefore, to describe this technique an alternate name is often used: Ferromagnetic Nuclear Resonance (FNR). The spectrometers and methods developed in the team during the last decades [1] allowed successfully studying the structure the morphology and the magnetic properties of ferromagnetic materials ranging from new permanent magnets [2] to multilayers, thin films and hybrid heterostructures [3]. In order to further increase our understanding in the properties of ferromagnetic systems we have developed very recently a new state of the art FNR spectrometer that opens up a completely new and very broad field of investigation for FNR. For this project we will focus on metal/organic heterostructures. The samples will be grown in the UHV system of the laboratory and analyzed with conventional techniques (XRD, Magnetometry…) simultaneously to the development of new spin polarization FNR sequences. New analyses methods and accompanying software might have to be developed also.
