Controlling skyrmions for better electronics

Physicists at the University of Hamburg managed for the first time to individually write and delete single skyrmions, a knot-like magnetic entity. Such vortex-shaped magnetic structures exhibit unique properties which make ...

Quantum storage system with long-term memory

(Phys.org) -- Credit cards which are completely fraud-proof and passports which cannot be forged: quantum physics could make both of these possible. This is explained by the fact that the quantum mechanical state of a particle, ...

Bit data goes anti-skyrmions

Today's world, rapidly changing because of "big data", is encapsulated in trillions of tiny magnetic objects - magnetic bits - each of which stores one bit of data in magnetic disk drives. A group of scientists from the Max ...

Dual 8-bit breakthroughs bring AI to the edge

This week, at the International Electron Devices Meeting (IEDM) and the Conference on Neural Information Processing Systems (NeurIPS), IBM researchers will showcase new hardware that will take AI further than it's been before: ...

An electrical switch for magnetism (w/ Video)

Researchers at MIT have developed a new way of controlling the motion of magnetic domains—the key technology in magnetic memory systems, such as a computer's hard disk. The new approach requires little power to write and ...

An advance toward ultra-portable electronic devices

Scientists are reporting a key advance toward the long-awaited era of "single-molecule electronics," when common electronic circuits in computers, smart phones, audio players, and other devices may shrink to the size of a ...

'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 ...
