Magnetic nanofibers are of high interest for applications like data transport and storage as well as in basic research. Especially bent nanofibers, as they can unambiguously be produced by electrospinning [1], show a broad spectrum of possible magnetization reversal processes, depending on bending radius, geometry, magnetic field orientation, etc. [2].
Besides these quasistatic processes, dynamic investigations are necessary for investigating data transport properties of magnetic nanofibers. We report on domain wall transport through nanowires with different bending radii, starting from single nanowires to networks with multiple data inputs and outputs. Our results show diverse phenomena which have to be taken into account during these dynamic processes, such as domain wall instabilities or interference between converging signals, and suggest possible architectures of nanowire-based logics.
