Tailoring Magnetic Properties of Iron by Non-Equilibrium Interstitial Engineering in Thin Films


It has been predicted that soft magnetic iron can be transformed into a material with high magnetocrystalline anisotropy by tetragonalisation. This tetragonalisation can in principle be achieved by interstitial atoms such as B, C and N, but their solubility in Fe is extremely limited. By applying new non-equilibrium methods during thin film growth, the limits of the tetragonalisation achieved so far are to be pushed into ranges that are also relevant for applications. The project will develop a precise understanding of the causes of magnetic anisotropy in close cooperation with materials modelling and establish interstitial defect control experimentally.
