Achieving superconductivity under normal conditions (at temperatures around 300K and normal pressure) is the primary goal of the entire V.L. Ginzburg Center.
To accomplish this task, the scientific team, in collaboration with synthesis and theoretical groups, conducts a wide range of studies on new materials, metamaterials, and nanostructures. The facilities available to the team enable the investigation of material properties at extremely low temperatures, as well as under ultra-high pressures (up to 2 million atmospheres) and in fields of up to 21 Tesla. In the process, all the main critical parameters of new superconducting materials are determined—critical currents, critical magnetic fields, coherence length, penetration depth, order parameter, and its structure.
Research tasks
1. Development of high-temperature superconductors with critical temperatures up to room temperature;
2.Investigation of the physical properties of new superconductors, including polyhydrides at megabar pressures;
3. Study of the transport and magnetic properties of new high-temperature superconductors (HTS) under strong magnetic fields (up to 16 Tesla), in the temperature range from 50 mK to 300 K, and pressures up to 2 megabar;
4. Creation of mesostructures and nanoscale sensors for magnetic research (SQUID magnetometers, susceptibility meters, voltage standards, etc.) using UV and electron lithography, as well as focused ion beam etching with nanoscale resolution;
5. Investigation of phase transitions in the vortex state of superconductors with different types of order parameter symmetry (s-wave, d-wave, s-extended, etc.);
6. Study of the behavior of superconducting carrier density in the latest superconductors with complex Fermi surfaces, as well as in the presence of competing orders (magnetic, charge density wave, etc.) in the superconductor;
7. Tunneling studies using scanning tunneling microscopy (STM), tunneling spectroscopy (STS), and Andreev spectroscopy of symmetric (SNS) and asymmetric (NS) contacts;
8. Investigation of the properties of new topological materials with magnetic ordering;
9. Study of the properties of new HTS and superconducting compounds with broken symmetry elements (T-inv, P-inv), exchange, and spin-orbit interactions.
