Nanoscale vortices

Argonne materials scientist Mihaela Tanase observes a small magnetic disk with a transmission electron microscope. At Argonne's Center for Nanoscale Materials, Tanase discovered a new method to control the way the atoms in the magnetic disk orient themselves to form " nanoscale vortices," which are illustrated on the computer screen.
