Introduction to Section C: High-Temperature Superconductors
Published in David A. Cardwell, David C. Larbalestier, I. Braginski Aleksander, Handbook of Superconductivity, 2023
The discovery of cuprate high-temperature superconductors (HTS) by Bednorz and Mueller in 1986 [1] brought about a revolution in both materials development and in the techniques used to characterize them. Coming as it did at a time when interest and funding investment in superconductivity was in decline, the discovery of HTS injected a huge resurgence of research activity and the establishment of national programs directed toward a coordinated, multidisciplinary, multi-institutional approach to investigating, understanding and exploiting HTS. The study of HTS has greatly enhanced the sensitivity of techniques like angle-resolved photoelectron spectroscopy (ARPES) and promoted the shift from synchrotron-based ARPES to laser-based ARPES with its higher resolution and greater probing depth. The promise of applications has also accelerated the development of refrigerator systems, both in terms of efficiency and miniaturization.
Superconducting Transformers

High-temperature superconductivity has great potential in electric power applications (generators, motors, fault current limiters, transformers, flywheels, cables, etc.) as losses and sizes of devices are significantly reduced. The technology is now mature, and prototypes are considered. The ability to predict and reduce all “cold” losses is crucial to show economic advantages of HTS designs.
Modern Electrical Power Systems
Published in J.C. Das, Power Analysis Handbook: Short-Circuits in AC and DC Systems, 2017
Superconductivity has a wide field of applications not only in electrical power, but in many other fields. It can revolutionize the future technologies. The superconductivity was discovered by Dutch physicist, H.K. Onnes, in 1911. Since 1960, a Niobium–Titanium (Ni–Ti) alloy has been the material of choice for commercial superconducting magnets. More recently, a brittle Niobium–Tin inter-metallic material has emerged. In 1986, an oxide-based ceramic material demonstrated superconducting properties above 35 K. A superconducting material with critical temperature above 23.3 K is called high-temperature superconductor (HTS).

Recently, high temperature superconducting (HTS) material technology has become mature gradually, and an increasing number of superconducting electric devices have been applied in the power industry. Technically, the utilization of superconducting electric devices offers great potential to strengthen the system performance, such as the enhancement of power system stability, the reduce of power operation loss and the improvement of power system reliability [1–4].
