Moscow State University (MSU) has conducted research on new superconductors that could form the basis for future electronics. We tell you more about what Moscow scientists have done.
Employees of the Department of Low-Temperature Physics and Superconductivity of the Faculty of Physics have for the first time studied the superconducting properties of a new class of iron-containing pnictides, known as 1144 — CaKFe4As4. In the course of the work, they managed to measure their key energy parameters. This opens up new perspectives for the study of high-temperature superconductivity.
CaKFe4As4 superconductors, despite the relatively low critical transition temperatures to the superconducting state (up to 35 K), demonstrate high critical magnetic fields, which makes them suitable for use in nuclear and synchrotron technologies. An interesting feature of these materials is their non-magnetism, which distinguishes them from other pnictide families and makes them attractive for fundamental research.
As a reminder, iron-containing pnictides are a class of materials containing iron and a pnictogen (As) in their chemical structure. These compounds belong to the group of high-temperature superconductors, which exhibit superconductivity at relatively high temperatures compared to traditional superconductors.
Synchrotron technologies are methods and devices that use synchrotron radiation created in synchrotron particle accelerators. A synchrotron is a special type of accelerator that accelerates charged particles, such as electrons, to extremely high energies and directs them along a circular path using magnetic fields.
