Magnetomechanical Interactions in Freestanding, Ferromagnetically Filled Carbon Nanotubes — •Stefan Philippi, Uhland Weißker, Markus Löffler, Thomas Mühl, Albrecht Leonhardt, and Bernd Büchner — Leibniz Institute for Solid State and Materials Research Dresden, Dresden, Germany

The extraordinary mechanical properties of carbon nanotubes (CNT) yield enormous potential for applications in nano-electromechanical systems (NEMS). Yet almost all of the proposed or already implemented NEMS are actuated via electrical effects. Employing CNT with ferromagnetic filling will offer alternative applications for magnetically driven NEMS, if both their magnetic and mechanical properties are equally well understood. In this talk, several static and dynamic effects of applied magnetic fields on filled CNT are discussed with regard to fundamental analyses of their magnetomechanical properties as well as basic principals for potential applications.
