A team of researchers from Diamond, Exeter, Grenoble and Leeds have published a new paper describing interesting results from a new experiment - magnetic lensless imaging by Fourier transform holography using extended references. Characterization of magnetic states on the submicron scale could lead to rapid advances in understanding and utilizing the properties of new materials for spintronic devices.
The team reports clear images of magnetic domains in a Co/Pt multilayer thin film with perpendicular magnetic anisotropy. This technique can directly image magnetic configurations within an applied field and could help to advance magnetic logic and race track memory devices, which require an understanding the propagation and controlled pinning of magnetic domain walls along nanowires.
