'Rattle memory', new computer memory thanks to nanotechnology

Dutch researchers from the Eindhoven University of Technology have successfully made a 'magnetic domain-wall ratchet' memory, a computer memory that is built up from moving bits of magnetised areas. This memory potentially offers many advantages compared to standard hard disks, such as a higher speed, lower electricity consumption and much longer life. Using concentrated ion bundles the researchers have influenced the magnetic wires the bits move through, and they have successfully controlled bits at the nanometre scale and subsequently constructed a new memory. The research results were published online by Nature Nanotechnology on July 15.
