Abstract

The magnetic properties of soft magnetic nanotubes with a transverse anisotropy are investigated by means of numerical simulation. The structure of isolated bamboo domain wall and its evolution under the influence of axial uniform magnetic field, as well as a circular magnetic field of a DC current is investigated. Also the stability of various bamboo domain structures (BDS) in axial and circular magnetic fields is studied. It is found that the magnetic field that saturates a nanotube in axial direction is close to the anisotropy field. On the other hand, the interval of circumferential magnetic fields where a BDS can exist is two orders of magnitudes shorter.
