  Magnetic nanotubes have been widely studied because they are promising
candidates to be part in devices based on spintronic and magnonic technologies.
However, the experimental techniques used to prepare these elements could not
guarantee to have perfect nanostructures. Therefore, some geometric
imperfections can appear. In this direction, the bent of a nanotube could play
an essential role in the magnetic properties of a device. In this work, we
analyze the influence of curvature on the magnetic properties of a bent
nanotube, a topic scarcely studied, and that can have a strong impact on
applications.
