High-Tc Superconductors: Limitations and Applications When high-temperature superconductivity was found by Bednorz and M¨ uller in 1986 [15] many research activities were started all over the world. This was not only because of the desire for even higher critical temperatures Tc . But the possibility of cooling with liquid nitrogen instead of liquid helium made the application of superconductivity in energy technology much more probable and economically feasible. The great expectations, however, had soon to be scaled down. Despite having high transition temperatures of e.g. 94 K in YBa2 Cu3 O7−δ or even 110 K in (Pb,Bi)2 Sr2 Ca2 Cu3 O10 , the new ceramic superconductors could not carry very high critical currents Ic . Thus technical applications again turned out not to be around the corner and big effort was put into the understanding and elimination of critical-current limitations. Yet there are some important properties of high-temperature superconductors (HTSCs) besides the high transition temperature. In principle they have a very high upper critical field (up to 100 T for the bismuth superconductors) and could thus carry high currents at much higher fields than the conventiona
