Magnetic Solitons Created
In the past decade the computer has not made any fundamentally significant changes, but in the next ten years or so, that may change. Researchers are working to create a new kind of computer that operates on the spin of electrons instead of on their charge, like modern computers. Now those at North Carolina State University have successfully created a magnetic soliton, which could prove invaluable for spintronic computers.
Solitons are a special kind of wave which is self-reinforcing and thus able to preserve its size and momentum over distances. They have been known about for years, but the idea of a nano-sized magnetic droplet was only suggested 35 years ago, and now one has been created. To achieve this, the researchers pushed a DC current through a magnet, causing the electrons within it to tilt their magnetic axes. The electrons then began to precess because of this leaning, which created the magnetic soliton in the form of a spinning droplet.
Due to their self-reinforcing nature, the researchers see magnetic solitons potentially being used within spintronic computers to transmit information or even to create more advanced magnetic hard drives.
