Ferrimagnets play a key role in revolutionizing spintronic devices due to their favorable properties including low saturation magnetization and ultrafast spin dynamics. An in-depth understanding of the underlying mechanisms is paramount for the integration of ferrimagnets in next-generation memory technologies. For this, imaging the magnetic domain structure is a powerful tool. One method of visualizing magnetic textures are vector maps providing the opportunity to analyze the evolution of the orientation of the Néel vector. This poster will give detailed insight into constructing vector maps from x-ray magnetic linear dichroism images revealing the magnetic domain structure in Dysprosium Iron Garnet (DyIG) thin films. As this approach is based on an angle-dependent examination of the alignment of the Néel vector, this technique offers the possibility of expanding it to antiferromagnets.
