Investigation of magnetic texture of CuMnAs by holography assisted coherent diffractive x-ray imaging

With rapid evolution of spintronic devices, it becomes more and more crucial to study domain structures and dynamics in compensated magnetic materials. The well established methods often suffer from limited spatial and temporal resolution, sensitivity to external magnetic field or inability to detect signals where stray fields are absent. On the other hand, the pressure to downscale and speed up forces the community to explore magnetic structures at the very forefront of magnetism. The immense progress in understanding of the unique magnetism in CuMnAs, the workhorse material of antiferromagnetic spintronics and which was enabled by XMLD-PEEM imaging seems to be at its limits. We propose to employ holography assisted coherent diffractive x-ray imaging to study magnetic textures in CuMnAs from a different perspective offered by this method.
