• ITMO Scientists Prove Skyrmion Laser Manipulation

  In recent years the leaders of the global semiconductor industry - companies such as Intel and IBM - have faced inability to accelerate the speed of modern computing systems by increasing the density of microprocessors per unit area. This is caused by fundamental physical limitations. However, it initialized the search for new models and methods of their implementation. Electronics of the future will be based on this research. One of the fields that scientists suggested was spintronics and its subdivision - skyrmionics, which studies exotic magnetic ring formations called skyrmions. They were first obtained in a laboratory in 2010. In the future they may find use in development of more efficient memory chips. Like graphene in the field of nanomaterials, skyrmions can lead the way to go beyond 10-nanometer technological process of chip production. Researchers at ITMO University are also working in this field and have recently managed to demonstrate in theory that properties of skyrmions can be controlled using external laser radiation. The results of this work were published in the Physical Review Letters.
