Scientists from Siberian Federal University and the Federal research centre of Krasnoyarsk scientific center SB RAS synthesized nanoparticles of copper oxide, which can be based on superconducting materials at room temperature. The article is devoted to the study of the magnetic properties of the particles published in the September issue of Journal of Superconductivity and Novel Magnetism.

One of the most important characteristics of the material used for the grid — his ability to conduct an electric current. Each material has a resistance property to dissipate, and hence slow down the electrons, the directional movement is called current. However, in 1911, was opened superconductor material, which showed zero resistance when lowering the temperature to 4 K. the Scientists continued the search and found many similar materials. But their practical application was impossible because of the need to maintain a low temperature (from -273,14 °C to -253,15 °C).

A breakthrough in superconductivity was the discovery materials that showed zero resistance at higher temperatures from -196 °C. researchers found that high temperature (0 °C) superconductors can be used for a new generation of power grids, potentially with greater bandwidth. It also includes the creation of high-speed trains on magnetic levitation, powered by superconductors.

Three years ago the staff of the Siberian Federal University and the Federal research centre of Krasnoyarsk scientific center SB RAS synthesized nanopowder of copper oxide with the chemical formula CuO2 for potential use in superconductors. For obtaining nano-powders (powders of particle size of several tens of nanometers), the researchers used the method of vacuum arc plasma evaporation. It provides deposition of thin films in vacuum by using a plasma discharge.

In nature there is a compound of copper oxide one atom of oxygen and one atom of copper. But thanks to the introduction of one oxygen atom in the compound, nanoparticles of such molecules become magnetic properties in a certain range of magnetic field (>3 kOe). These properties are characteristic of superconductors. The researchers said that if we manage to unite the powder particles in a single material, most likely, it will work as a superconductor at room temperature and even higher. And this, in turn, opens up new prospects.

In the U.S., Japan, China and the EU is actively conducting fundamental and applied studies of the current-carrying elements on the basis of high-temperature superconductors. Despite substantial progress in their creation, while the scientific results have not yet received practical application.

«We only need to connect the powder of nanoparticles of copper oxide. This would mean that we got a new superconductor that will work at room temperature. It really reduce the cost of fabrication, increase reliability and service life, to create a power system with qualitatively new characteristics acceptable to the electricity of the XXI century — says the head of the Scientific-educational center UNESCO «New materials and technologies» of Siberian Federal University Anatoly Lepeshev. — It should be noted ecological perfection of superconducting electrical equipment at a lower capital cost in mass production. The increase in current density, increase specific power, and specific, unique to superconductors physical properties create preconditions for the development of high types of electrical engineering.»
