Abstract	The size of magnetic features in modern materials, i.e. magnetic domain walls, vortices or skyrmions, can be at length scales below 100 nm. Imaging them requires methods with advanced resolution capabilities like ptychography, a combination of diffraction imaging and scanning transmission microscopy. Ptychography can achieve potentially wavelength limited resolution [1] over extended sample areas using an iterative reconstruction algorithm which provides phase and amplitude information. Resonant X-ray ptychography for imaging of magnetic domains using hard [2] and soft Xrays [3] has shown significant improvement of resolution in comparison with conventional X-ray imaging techniques. The goal of this work was to understand limitations and advantages of ptychography for imaging of magnetic materials by studying domain labyrinth and skyrmion samples, with special focus on comparing the results of ptychographic imaging with classical STXM.
