The emerging ability to control matter at the most fundamental level has enabled production of novel, low-dimensional structures with tailored features and functionalities. The structural and electronic properties of these systems can be directly measured by several experimental techniques, e.g. scanning tunneling microscopy (STM), angle-resolved photoemission spectroscopy (ARPES) or X-ray absorption spectroscopy (XAS), while magnetic properties are successfully measured applying X-ray magnetic circular dichroism (XMCD). Due to an enormous growth in computing power and advances in numerical methodologies during the last decade, the computational modelling of materials has matured to the stage which allows description of the properties of studied structures with time and spatial resolution not always accessible even with the cutting-edge experimental methods. The main scientific aim of this project is to combine world class expertise and experimental infrastructure of the research group from EPFL with high level competence in the computational modeling of materials, acquired by Serbian research teams from Vinca Institute and Institute of Physics, both located in Belgrade, to investigate magnetism in transition metal nanostructures grown on graphene and hexagonal boron-nitride (h-BN). The synergy between experiment and theory will provide insights into physical properties of the studied structures, with the level of details which is beyond capabilities of any of applied methods alone. Specifically we plan to study:(i) spin and orbital magnetism of small Fe and Co clusters on a free-standing graphene and h-BN layer.(ii) structural and magnetic properties of Fe and Co clusters on graphene and h-BN grown on close-packed surfaces of Pt, Ni and Rh.(iii) substrate effects on the magnetism in Co adatoms on graphene supported by Ir(111) and Ru(0001).(iv) structural properties of Co or Ni films deposited on graphene grown on ferromagnetic transition metals (Co and Ni), together with the spin-transport in these heterostructures.(v) spin-transport in Co/graphene/Co(0001) and Co/h-BN/Ni(111) sandwich structures with the focus on the role of the h-BN barrier.In addition to anticipated high level research results, the project will strengthen networking of Serbian researchers with top class European research groups and institutions, and enhance quality of the training programs of four young scientists, members of research teams from Vinca Institute and Institute of Physics Belgrade.The project also offers opportunity to use visits of EPFL team members to Belgrade to transfer their highly valuable knowledge and skills in experimental condensed mater physics to Serbian scientists. This will enrich scientific activities and competence of researchers at Vinca Institute and Institute of Physics Belgrade, as well as at Nano Center Belgrade, a new national shared facility institution expected to start its operation by the end of 2013. Since the studies planned within this SCOPES project will utilize graphene as a key material for engineering of magnetic nanostructures, the project will have a favorable impact on the aims of Serbian research teams to actively participate in recently launched large-scale GRAPHENE FLAGSHIP project of European Commission.
