Speeding up data storage by a thousand times with 'spin current'
Eindhoven, Netherlands (SPX) Jul 11, 2014 - A hard drive stores bits in the form of tiny magnetic domains. The directions of the magnetic north and south poles of these domains, which are referred to as the magnetization, determine whether they are a 0 or a 1. Data is stored by changing the direction of the magnetization of the associated bits. At present this is done using a write head to create a local magnetic field, which makes ... more
