Chapter 4 Basic Milestones in the Study of Superconductivity
However, the creation of high-Tc superconductors has not led to a revolutionary
breakthrough in technology and industry. Ceramics were too low-technological to
manufacture a thin superconducting wires. Without wires, the using of high-Tc
superconductors had to be limited by low-current instrument technology. It also did not
cause the big breakthroughs in this manner, either (see, e.g. [31]).
After discoveries of high-Tc superconductors, no new fundamental breakthrough of
this value was made. Perhaps the reason for this is that the BCS-theory, adopted by most
researchers to date, can not predict the parameters of superconductors apriori and serves
as just a support in strategy and tactics of their research.
