A scientific group from MV Lomonosov Moscow State University has successfully grown large single crystals of new superconductors and studied their crystal and electronic structures. Superconductivity allows materials to conduct lossless electric current at low temperatures, and although the phenomenon has been studied for more than a century, scientists still have much to understand. Recent developments in this field, including copper and iron superconductors, highlight their enormous potential for applications in technologies such as quantum computers and medical imaging.
The researchers emphasize the importance of obtaining large single crystals because they provide more accurate information about physical properties compared to polycrystalline samples. Crystals that grow up to 4 mm in size are of higher quality and allow properties to be studied in different directions. This information is necessary for the development of superconductivity theory and the creation of new compounds that could have a significant impact on industry and everyday life.
Professor Igor Morozov from Moscow State University shared that the idea of studying new compounds arose after the discovery of superconductivity in some bismuthides. The researchers managed to create large single crystals of layered bismuthides with the formula BaTM1.8Bi2, where TM is a transition metal. They found that the resulting compounds have a unique structure that could indicate the existence of superconductivity. In the future, scientists plan to test their properties at low temperatures to confirm their hypothesis.
