Laboratory for Quantum Nanospintronics Research
This laboratory was established as part of a scientific research project supported with a monetary grant awarded by the Government of the Russian Federation under a grant competition designed to provide governmental support to scientific research projects implemented under the supervision of the world's leading scientists at Russian institutions of higher learning (Resolution of the RF Government No.220 of April 9, 2010).

Name of the institution of higher learning:
Institute of Metal Physics, Ural Branch of Russian Academy of Sciences
Fields of scientific research:
To investigate the passage of microwave signals generated by spin waves through magnetic micro- and nanostructures while injecting them with spin currents. The key idea is to obtain a profound understanding of the process of propagation of waves within nano-scale magnetic structures, and to design techniques for application of dynamic magnetic phenomena at the nano-scale with the view to create a new generation of highly integrated components and devices for data transmission and processing within the microwave frequency range.
- To create a new generation of highly integrated components and devices for data transmission and processing operating within the microwave frequency range with previously unachieved parameters that are based on magnetic nanostructures with controllable losses and noises.
- To design hybrid structures containing magnetic and nonmagnetic layers and demonstrating insignificant losses.
The project has helped design magnon-based micro-scale devices of a new generation. The researchers have obtained a profound understanding of the interaction between spin waves and spin currents at the micro- and nano-scale. The project team has designed and manufactured analogue microscopic magnon-based devices used to process microwave signals, such as time-delay lines whose delay coefficient significantly exceeds that of spin waves, as well as microwave generators with an ultralow noise level and rapid narrowband filters. The project team has designed and manufactured digital integral magnon-based devices. The project team believes the scope of research of the newly created laboratory may expand in the future and the laboratory will be able to successfully engage in technology transfer by supplying production industry with new functional materials.
