Scientists explore ways to synchronize spins for more
powerful nanoscale electronic devices
Scientists at the U.S. Department of Energy's Brookhaven
National Laboratory are seeking ways to synchronize the magnetic spins in
nanoscale devices to build tiny yet more powerful signal-generating or
receiving antennas and other electronics. Their latest work, published in
Nature Communications, shows that stacked nanoscale magnetic vortices separated
by an extremely thin layer of copper can be driven to operate in unison,
potentially producing a powerful signal that could be put to work in a new
generation of cell phones, computers, and other applications.
