Future computers could be built from magnetic 'tornadoes'
Sheffield, UK (SPX) Oct 17, 2014
Magnetic materials form the basis of most hard disc drives as they are able to store data. A team from the University of Sheffield's Faculty of Engineering have been investigating whether they could also be used to perform calculations, and so take on the role of a computer's central processing unit (CPU). Lead researcher, Dr Tom Hayward, explains: "Magnetic materials are useful for data storage because they can retain information without consuming energy. A computer built around a CPU made of mag ... read more
