Magnetism to increase computer memory
Magnetic materials, built up as multi-layered sandwiches with successive layers only a few atoms thick, are giving computers larger memories. By building up sandwiches of magnetic and non-magnetic materials one layer of atoms at a time, it is possible to manipulate, enhance and control the magnetic properties of such sandwiches with extraordinary precision.
This is making it possible to design data storage and movement sensing devices, which are tailor-made on an atomic scale for specific tasks. Scientists at the University of York are researching the properties of new and exotic magnetic sandwiches, which will be put to work not only in data storage but in vehicles in engine control, anti-skid devices, speed control and crash-avoidance systems.
