FEFU specialists create a new fast and non-volatile electronic memory

On the basis of the Far Eastern Federal University (FENU), one of the researchers Oleg Tretyakov together with colleagues from the US, Japan and Germany are working on a very fast, cheap and next-generation non-volatile memory. The basis for creating a memory served as a so-called Hall effect skyrmions.

The elements of a new type of memory can be the basis of future magnetic storage technologies. All modern hard drives for storing information using a kind of "cell", the minimum physical size of which has already reached 100 nanometers, and further reduce them will not work. Using skyrmions (topologically incorrect configuration with a magnetic spin vortex-like structure) can be reduced to a size of several nanometers, which will use them for data storage and processing devices with higher density. In addition, this memory will store information even when power is off, which is very important for data backup. That skyrmions expected to be used in future applications of spintronics - "memory on the treadmill" Racetrack Memory and logic devices.

"Based on skyrmions is already underway to develop new storage systems and data processing. These memory cells are cheaper to produce, they will run faster and more reliably, consume minimal power. In the future, they can be used in the production of nanoelectronics devices - computers, smartphones, sensors are able to work for a long time without recharging, "- said a leading researcher of the Laboratory film technologies School of Natural Sciences FEFU Alexander Samardak.
