A method for the postdeposition organic coating of metallic nanoparticles is introduced. FePt nanoparticles from the gas phase are deposited onto Si substrates which are pre-coated with multilayers of phospholipid molecules by spin coating. If the substrate temperature is just below or above the temperature, at which the phospholipids undergo a phase transition from the liquid crystalline into an intermediate phase, the particles are enwrapped by the lipids. The particles exhibit a clear tendency to self-assemble in regular two-dimensional particle arrangements.

    We pattern submicrometer structures of thin films of permalloy in the form of two crossing ellipses and in the form of one long ellipse crossed by several ellipses where the width of the ellipses varies between 100 and 1000 nm. We find that the crossing area has two stable axes of magnetization,...

    Chemical ordering of (111)-oriented CoPt ultrathin continuous layers in CoPt/AlN multilayer structure has been investigated. It is found that upon thermal annealing at 600 °C, CoPt layers undergo ordering transformation even when the CoPt layers are as thin as 2 nm. The degree of ordering...

    Magnetic anisotropy of Co40Fe40B20 thin films sandwiched between Ta and MgO layers was investigated. Magnetic properties of CoFeB layers deposited on top and bottom of MgO layer are different. The thickness of the CoFeB layer and annealing temperature are the critical parameters to achieve and...

    A soft/hard Fe/FePt bilayer with perpendicular magnetization was prepared on a glass substrate. Annealed Fe/FePt film allowed modification of the Fe/FePt sharp interface to Fe/(Fe-rich FePt)/FePt graded interface with rigid magnetization due to the nanoscale soft/hard interface coupling.

    Ultra-thin FePd films were prepared by the sputter-deposition of Fe and Pd layers. After annealing at 500 °C, they transformed to a (001) oriented L10 ordered phase from an A1 disordered phase and changed their anisotropy to perpendicular magnetic anisotropy from in-plane. The ordered...
