Physicists from Russia the first has studied properties of "impossible" superconductors - RIA Novosti, 8/23/2018


MOSCOW, 23 Aug – RIA Novosti. The Russian physics has obtained the first data on structure and behavior of the "impossible" superconductors combining properties of magnetic and sverprovodyashchy materials. Their conclusions have been presented in the Science Advances.© magazine of the Photo: MIPT/Nii et al. / the Russian scientists have tracked Nature Communications 2016 magnetic whirlwinds in memory of the future "our results open the new page in modern physics of superconductivity, they give the soil for future basic theoretical and pilot studies of the processes proceeding in superconductors at an atomic scale. We prepare a number of scientific articles about such materials, and this publication became the first in own way" — Vasily Stolyarov, the physicist from Moscow Institute of Physics and Technology in Dolgoprudny whose words are cited by the press service of higher education institution has said. All superconductors have unusual property – they don't love" magnetic field and seek to push out him outside in case lines of this field contact to them. If force of the field exceeds a certain value then superconductor sharply loses the properties and becomes "usual" material. Scientists are interested long ago how this phenomenon which they call "Meysner's effect" will influence behavior of data carriers and computing devices and also ferromagnetic superconductors, a new class of substances with a zero resistance. Long time physicists considered that such substances can't exist as magnetic fields prevent formation of couples of electrons which are responsible for work of superconductivity. At the beginning of this century it has become clear that it not so when physics has opened several compounds of rare-earth metals, sulfur and the pine forest combining and superconducting, and magnetic properties. It isn't clear yet, how exactly they work, however scientists assume that electrons in them can unite not in couples, and in peculiar three, and ferromagnetic superconductors can be broken into the alternating zones with superconducting and magnetic properties. © Illustration of RIA Novosti. Alina Polyanina//Yonathan Anahory/Hebrew University of Physics have opened the fastest object on Zemlestolyarov and his colleagues from the Russian and foreign scientific centers have taken the first step to disclosure of mysteries of these materials, studying behavior of the similar layers arising in crystals from compound of europium, iron, arsenic and phosphorus at low temperatures. This material as scientists note, is unique and interesting that it gains superconducting properties before he turns into a magnet whereas other ferromagnetic superconductors behave back. The similar unusual line of this connection has allowed Stolyarov and his colleagues to track formation of layers and behavior of electrons in him, using a magnetic and power microscope. These observations have helped scientists to find a phenomenon which they didn't expect to see. Besides magnetic domains, superconducting currents and the related "magnetic funnels", so-called whirlwinds of Abrikosov
