Nanoscale Stacked Magnetic Vortices (image) DOE/Brookhaven National Laboratory Share Print E-Mail Caption Stacked nanoscale magnetic vortices (blue and green discs) separated by an extremely thin layer of copper can be driven to oscillate in unison, potentially producing a powerful signal that could be put to work in a new generation of cell phones, computers, and other applications. This illustration shows an array of such stacked vortices, each measuring a few hundred nanometers in diameter.
