A Local Method of Analyzing Physical Processes in High-Temperature Superconductors on a Vortex Front

A local approximation procedure for investigating the magnetic microstate of high-temperature superconductors is developed, which enables useful information to be obtained simultaneously on the crystal microstate of the sample. By probing the volume of the sample using an alternating attenuating magnetic field front, it becomes possible to isolate and investigate the physical processes in superconductors, which occur on the vortex front. Qualitatively new results are obtained for samples with different microstructures.
