PC Revue | The new bases for future magnetic storage can be skyrmions

Scientists from Birmingham University, Bristol and Colorado Boulder are developing a new generation of storage and data processing devices using a new science called skyrmionics. Skermata focuses on the utilization of the properties of nanometer structures in magnetic foils called skyrmiony. They belong to the field of spintronics, they have a size of one nanometer and a magnetic spin similar to a small vortex.

Scientists believe they can be used for much more dense storage of data from existing technologies that rely on modern computing. The shape of the skyrmions enables data encoded in them to convey with much less performance than can be achieved today. However, the arrangement of these new structures in a way that can be stored and transmitted data is a problem.

In a new study published in the journal Natural physics, a research team of British theorists and American experimental scientists have shown a way of combining multiple skyrmions in structures called "skyrmion packets" and contain several skyrmions, allowing more information to be stored in even narrower space. Thus, he modeled his technology using computer simulations and then successfully tested it in real conditions of liquid crystals.

"It's very exciting to see this technology work in liquid crystals because it opens up new opportunities for progress in areas such as displays, sensors and even solar cells" says co-author of the study, PhD. David Foster of the University of Bristol. However, it is not yet possible to predict when we will meet real products based on this technology.
