Imaging the magnetisation vector field by Fourier Transform Holography

Fourier Transform Holography (FTH) is an established microscopy technique with nanoscale resolution providing images of one projection of the magnetic moments in a thin sample. We propose to extend the scope of the technique by realizing a full vectorial determination of the magnetic moments in two test samples: one with Landau domains around a vortex core, and one with a skyrmion lattice. This improvement is highly desirable for the study of materials with complex magnetic textures such as skyrmions, chiral domain walls, Bloch points, etc...
