Scientists at Birmingham, Bristol and Colorado Universities, Boulder have moved a step closer to developing the next generation of data storage and processing devices, using new science of the name skyrmionics.

Skyrmionics focuses on harnessing the properties of nanometer size structures in magnetic films called skyrmions. These spins on the surface of the magnet as small bursts, and scientists believe they could be used to store much more data than is currently possible using current magnetic data storage techniques. modern computers rely on them at the moment.

The shape of these skate structures means that encoded data could also be transmitted using much less power than can be achieved at present.

But organizing these new structures in a way that makes them able to store and transfer data has been a challenge.

In a new study, published in 2007 Nature PhysicsThe research team of UK theorists and experimenters based in the United States has shown a way of combining multi-scrums with each other in structures they are calling & t Skyrmion bags, allowing much more information packing in skyrmion systems.

"The challenge of improving our data storage is becoming increasingly urgent," explains Mark Dennis, Professor of Theoretical Physics at Birmingham University and lead study author. "We will need new technological approaches to increase the amount of data we want to store in our computers, telephones and other devices, and skyrmins may be a way to do this. Instead of using single screw trains to encode binary pieces, each scrum bag can hold any number of scratches, increasing the potential for tremendous data storage. "

The team have modeled their technique in magnetic devices using computer simulations, and successfully tested them in experiments involving liquid crystals.

"It is particularly exciting to see this technology working in a liquid crystal as it opens up new possibilities for developments in areas such as display screens, sensors or even solar cells," adds the lead author t , Dr David Foster, University of Bristol.

Skyrmions was originally proposed as a theoretical model of fundamental particles by Professor Tony Skyrme of Birmingham University in the 1960s. This research, funded by the Leverhulme Trust and the US Department of Energy, shows how total theoretical ideas in physics can lead to innovative new technologies.
