Topological magnetic monopoles are non-local spin textures that are robust to thermal and quantum fluctuations, but they are difficult to study at the nanoscale in real space. Now, soft X-ray vector ptycho-tomography is demonstrated to determine the three-dimensional magnetization vector and emergent magnetic field of such magnetic monopoles in a ferromagnetic meta-lattice.
