Topologically protected magnetic solitons in curved permalloy films

Our main scientific objective is to explore topologically protected magnetic solitons that occur in highly ordered, three-dimensional magnetic nanomembranes. Our goal is to study complex hierarchical 3D nanoscale geometries, which consist of distinct magnetic subsystems. For this, we have developed a fabrication method for creating complex 3D nanoarchitectures as homogeneous arrays over centimeter scale. We will examine the impact of local curvature on the stabilization of different magnetic textures like vortices and antivortices, two Bloch lines hosted within the same nanoscale object.
The capabilities of the MISTRAL beamline will enable a 3D tomographic reconstruction of the present magnetic textures, providing deeper insights into the three-dimensional magnetization states of these complex geometries. Our successful preliminary measurements performed at MISTRAL beamline (manuscript in preparation) confirms feasibility of magnetic imaging of our samples. This study will contribute to the understanding of the role of nonlocal symmetry break on the stabilization of complex magnetic solitons in curvilinear geometries, which is relevant for potential applications in spintronic and magnonic devises.
