“…Even though coherent x-ray magnetic imaging is relatively young, it has already contributed uniquely to several milestone discoveries in the field of magnetism, as shown in figure 17. For example, in 2015, time-resolved x-ray holography was used to confirm the quasi-particle nature of magnetic skyrmions in [Pt/CoB] x30 up to the GHz regime [308] via tracking the skyrmion with sub-3 nm precision and thereby discovering that the equation of motion of a skyrmion includes a mass term, while static holography has been used to image the 3D shape of skyrmion tubes [327] and identify skyrmionics cocoons [328]. Later, PTY has allowed to resolve the actual profile of skyrmions in a similar [Ta/CoFeB/MgO] x16 magnetic multilayer [329], to map the 3D configuration of Bloch point singularities [309,317] as well as providing the first observation of magnetic vortex rings and torons [330], to name just a few.…”

Considering the growing interest in magnetic materials for unconventional computing, data storage, and sensor applications, there is active research not only on material synthesis but also characterisation of their properties. In addition to structural and integral magnetic characterisations, imaging of magnetization patterns, current distributions and magnetic fields at nano- and microscale is of major importance to understand the material responses and qualify them for specific applications. In this roadmap, we aim to cover a broad portfolio of techniques to perform nano- and microscale magnetic imaging using SQUIDs, spin center and Hall effect magnetometries, scanning probe microscopies, x-ray- and electron-based methods as well as magnetooptics and nanoMRI. The roadmap is aimed as a single access point of information for experts in the field as well as the young generation of students outlining prospects of the development of magnetic imaging technologies for the upcoming decade with a focus on physics, materials science, and chemistry of planar, 3D and geometrically curved objects of different material classes including 2D materials, complex oxides, semi-metals, multiferroics, skyrmions, antiferromagnets, frustrated magnets, magnetic molecules/nanoparticles, ionic conductors, superconductors, spintronic and spinorbitronic materials.
