MA 8: Focus Session: Magnetic structurally and compositionally modulated nanowires and nanotubes

Montag, 12. März 2018, 15:00–18:30, H 1012

There is an increasing scientific activity on magnetic nanowires and nanotubes with tunable circular section (as opposed to nanostripes). Length, diameter, shell thickness and materials can be selected from a wide range of magnetic alloys and elements. Axially and radially modulated structured can be synthesized. These families of cylindrical wires and tubes are currently proposed in a number of applications ranging from specific media for magnetic memory applications (race-track), microwave applications (stealth absorbing materials), magnetic sensing elements and logic devices at the nanoscale (nano-technology), or for applications based on their magneto-thermo-electrical properties (energy conversion and harvesting). Other relevant applications include their organic functionalization for a number of biomedical applications. Most of those applications derive from their unique magnetic characteristics namely the magnetic configuration (e.g., magnetic domains), demagnetization process (e.g., nucleation and depinning of transverse or vortex domain walls; coherent/non-coherent rotational processes), and frequency dependent behaviour (e.g., microwave absorption phenomena). In short, the motivation of this Mini-colloquium is to bring together specialists and scientists interested in novel applications of anisotropic nanostructures to discuss and exchange ideas on both fundamental and applied issues of these nanowires and nanotubes.
