What scientific discoveries await the humanity in the future? Today's fundamental researches are targeted at improvement of information technologies, systems for processing and storing information, as well as at creation of a quantum computer which in many aspects will change the world and people's lives.

Presently, scientists of South Ural State University are working in this area. In 2018, an article was published in Optics Letters journal, indexed in Scopus and Web of Science databases. The authors of the article are research fellows of the SUSU Laboratory of Functional Materials, Igor Bychkov
and Dmitry Kuzmin.

"Our work demonstrates that using the Faraday effect might lead to a sufficiently big value
ofmagnetic field. It is important to notice that creating an electromagnetic field localized in nano scales is a quite serious problem. Our method allows achieving this: to create a big-enough magnetic field which would be localized in a small-enough volume. These magnetic fields in nano scales can be used for various purposes. The most obvious one is magnetic memory for information storage systems," says Igor Bychkov.

The article
considerspropagation of electromagnetic waves in a nanostructure which includes a metal substrate, dielectric material and graphene. All elements of micro- and nano electronics are obtained by application of some material (as a rule, metal) on the substrate. It was graphene precisely that the scientists have chosen for the work as its properties are comparatively easy to control: it can change from a practically non-conducting material to a good conductor. This allows obtaining additional functionality of nanostructure.
