Continuous trends towards the miniaturisation of electronic devices and components require appropriate, non-destructive, technique for Material characterisation on sub-micron scale. The performance of Materials is determined by their properties at the microscopic level, particularly by the sizes of magnetic domains and their motion in applied fields. Therefore, it is important to develop high-resolution techniques to characterise the micro-magnetic and magneto-optical properties of new Materials. The goal of this proposal is to make use of the high-sensitivity of non-linear magneto-optical Kerr effect for non-invasive and non-contact high-resolution imaging of advanced magnetic structures. This will give the possibility for studying meso-scopic (and/or) structured magnetic films and devices on the nano-scale. We will utilise the particular surface and interface sensitivity of non-linear magneto-optics in combination with near field optical microscopy for the investigation of domain structure and its dynamics in ferromagnetic and anti-ferromagnetic materials and structures based on them. The sub-wavelength optical resolution of SNOM will enable us to visualise the polarisation evolution in anti-ferromagnetic/ferromagnetic structures and magnetic tunnel junctions. This will provide information on basic electronic, magnetic, and optical properties related to individual domains such as exchange anisotopy, re-magnetisation mechanisms as well as the influence of local structural inhomogeneities.
