Influence of concave and convex surfaces in DMI multilayer nanotubes on curvature gradient-mediated spin textures by X-ray tomography

A basic understanding of special curved 3D geometries on magnetization textures of advanced multilayers systems is crucial, both for fundamental questions in 3D nanomagnetism and for possible future low-power microelectronic devices. The objective of this proposal is to examine the impact of concave and convex surfaces in Dzyaloshinskii–Moriya interaction (DMI) multilayer nanotubes on curvature gradient-mediated spin textures using full-field Transmission X-ray Microscopy combined with magnetic X-ray tomography (MISTRAL beamline). This method allows high resolution and element-specific imaging of 3D magnetic structures. By systematically varying the direction and strength of curvature, we are able to experimentally demonstrate that the Dzyaloshinskii–Moriya interaction (DMI) can be manipulated through geometry, which may result in the formation of distinct spin textures or even potentially stabilize novel magnetic configurations not accessible in flat systems. 

For publishing results from a previous experiment at Alba, additional measurements on further similar samples to those used at the time are necessary. Since current data stem from a single sample, these new measurements will ensure reproducibility and broader characterization required by the referees. This is essential to strengthen the scientific rigor and finalize the manuscript for submission.

This proposal addresses new scientific questions while providing the necessary data from additional samples to finalize the publication. It thus strengthens both the research progress and the quality of the scientific output.
