On the basis of the Far Eastern Federal University (FEFU), Oleg Tretyakov, one of the researchers, together with his colleagues from the USA, Japan and Germany, are working to create an extremely fast, cheap and non-volatile memory of the new generation. The basis for creating the memory was the so-called skyrmion Hall effect.
Memory elements of a new type can become the basis of future magnetic memory technologies. All modern hard drives for information storage use a kind of “cell”, the minimum physical size of which has already reached 100 nanometers, and it will not be possible to reduce them further. The use of skyrmions (topologically incorrect configurations of a magnetic spin with an eddy-like structure) can be reduced to a size of several nanometers, which will allow them to be used to create data storage and processing devices with higher density. In addition, this memory will store information even when the power is turned off, which is very important for backup data storage.
It is expected that the skyrmions will be used in future spintronic applications - Racetrack Memory “memory on a treadmill” and logic devices.
“On the basis of skyrmions, the development of new data storage and processing systems is already underway. Such memory elements are cheaper to manufacture, they will work faster and more reliably, consume a minimum of energy. In the future, they can be used in the production of nanoelectronics devices - computers, smartphones, sensors capable of long-term operation without recharging, ”said Alexander Samardak, leading research associate of the Film Technologies Laboratory of the FEFU School of Natural Sciences.
