A recent breakthrough by researchers at the University of Cambridge has led to a new way of studying magnetic behavior on the smallest scales. By combining a new imaging technique with a powerful new algorithm, the researchers have been able to image magnetic fields with unprecedented spatial resolution. This opens up a world of possibilities for studying the behavior of magnetic fields on the smallest scales, from nanoscale magnets to the behavior of electrons within materials. This will be particularly useful for developing new materials for use in computing and electronics.
