Atomic electromagnets made from coils of individual gold atoms could prove valuable for nanocircuits and machines, a new study suggests.
Tomoya Ono and Kinkuji Hirose at Osaka University in southern Japan performed computer simulations to determine the electromagnetic properties of helical gold nanowires. These are rows of individual gold atoms twisted around a central axis - like a wire spring - which measure 0.6 nanometres wide by 5 nm long.
