Self-assembling magnetic nanorings allow for nonvolatile memory

A Purdue research team has created tiny magnetic “nanorings” less than 100 nanometers across that can store information at room temperature, using magnetic cobalt nanoparticles that self-assemble.

The nanorings' magnetic flux can be oriented clockwise or counterclockwise to represent binary numbers in magnetic memory devices.
The nanorings could serve as nonvolative memory for long-term data storage and random-access memory.
