Three-dimensional Magnetization Structures Revealed with X-Ray Vector Nanotomography
Researchers from Mesoscopic Systems (Prof. Laura Heyderman), from the Paul Scherrer Institute (PSI), and from the University of Glasgow have for the first time made visible the directions of the magnetisation inside a micrometre-sized magnet in 3D down to details ten thousand times smaller than a millimetre (100 nanometres).
The scientists developed an experimental imaging technique called hard X-ray magnetic tomography with which they could observe intertwining patterns and, within them, magnetic singularities called Bloch points that were predicted theoretically in 1965 but have only now been observed directly with these new measurements. The researchers published their study in the renowned scientific journal Nature.
