These whirls can be moved rapidly and reliably
along nanowires or other structures in future memories.
Physicist Stuart Parkin and his colleagues at the IBM Almaden Research Center in San Jose, Calif., set out to determine just how magnetized regions move
along nanowires when driven by electric current.
A device that slides magnetic bits back and forth
along nanowire «racetracks» could pack data in a three - dimensional microchip and may replace nearly all forms of conventional data storage
That latter characterization is certainly true of racetrack memory, a proposed scheme in which data bits, encoded as magnetized regions on nanowires, move back and forth
along the nanowire «racetrack» and past read / write heads.
The magnetization in the branches can be oriented in two different directions
along the nanowire axis, where each direction would serve as the «0» and «1» necessary for data storage and processing.
With the help of related structures on disease - causing bacteria, the researchers show that the protein's shape and form suggest possible ways for the bacteria to shuttle electrons
along the nanowire.

By applying a magnetic field to semiconducting
nanowires laid across a superconductor, you can move electrons
along these wires, creating two points in space that each mimic half an electron.
In the presented experiment they formed intersections using the same kinds of
nanowire so that four of these intersections form a «hashtag», #, and thus create a closed circuit
along which Majoranas are able to move.
The collective flipping of large numbers of metallic
nanowire atoms, forced by a large number of electrons in the electric current, moves the domain wall — and the data bits it separates —
along.
At the initial deposition stage — the lowest size range — the shells consisted of perfect cylinders in the 2D model, and they formed ultrasmall rings, or «nanorings», stacked
along the vertical direction of the
nanowire, in the 3D model.
