“…Beginning with the discovery of high-temperature superconductivity in perovskite systems containing oxygen by Bednorz and Muller [1,2], the literature on this topic has become a veritable avalanche, as works on fabrication of metal [3,4,5,6,7,8,9,10,11,12,13,14] and polymer [15,16,17,18,19,20,21,22,23,24,25,26] binder composites of various geometries possessing SC properties were undertaken, alongside with fundamental research.…”
