Tiny magnetic 'flowers' could expand how researchers image spintronic materials under stronger fields

Materials with magnetic nanostructures have a wide range of potential applications. One area is so-called spintronics, with devices that encode information in magnetic domains. These magnetic bits can be written, read and erased in a more energy-efficient way than bits in current semiconductor devices. Spin textures and magnetic domains in such materials can be investigated using nanoscale magnetic imaging techniques. For example, photoemission electron microscopy (PEEM), coupled with a magnetically sensitive detection mechanism.
