Karazin Kharkiv National University popup.description2  The degenerate interacting gases of strongly correlated electrons in the oxides of transition metal atoms; high-temperature superconductors that are bounded by the media with complex electrodynamic characteristics; interaction of alternating electromagnetic fields with high-temperature superconductors were the object of the study. The goal of the work was to improve the numerical code developed by the project developers for the analysis of experimental data from the superconducting line, with account for the geometry and internal structure of the power transmission line, as well as the ability to use additional materials to reduce the effect of the external magnetic field on the creation of zones of abnormal conductivity. The distribution of electric current density at the brazed seams of BSCCO and GdBCO tapes was investigated by scanning with a three-dimensional (3D) Hall sensor. After measuring the distribution of the three components of the intrinsic magnetic field induced by the electric current, the distribution of the current density near the tape was calculated by solving the inverse problem using the matrix method implemented in the code in MATLAB. Using this technique, profiles for the perpendicular component of the electric current passing through the common space have been successfully obtained.
