High Temperature Superconductors: Materials and Applications

Abstract

A ceramic high temperature superconductor called cuprate was discovered in 1986 by Bednorz and Muller at 135 K critical temperature (Tc). Ladik and Bierman demonstrated the idea of high temperature superconductivity (HTSC) by essential excitation of electrons in one chain of double standard DNA. The cuprates are consisted of stiff, fragile, and hard properties which are considered as the negative impact of cuprates superconductors. With the passage of time such drawback were removed and the cuprate superconductors were made capable for various applications. The breakthrough came in the history of superconductors when the iron based HTSC were discovered in 2006. High temperature H2S superconductors are designed at high pressure and Tc greater than 200 K in 2015. From the time of discovery of HTSC, superconductivity is used in different types of fields such as medical, electrical, magnetic, optics, recording media, microwave and communication devices.

Review on Microwave Surface Resistance of High Temperature Superconductor Yttrium Barium Copper Oxide

“…Yttrium Barium Copper Oxide (YBCO), a compound that was discovered in the late 1980s, is considered one of the most promising high-temperature superconductors [5,9]. This material, made up of yttrium, barium, copper, and oxygen atoms arranged in layers, demonstrates superconductivity at elevated temperatures when cooled below its critical temperature.…”

“…The efficiency of energy transmission and dissipation at high frequencies is quantified, affecting the overall performance of superconducting devices operating in the microwave and radio frequency ranges. Understanding microwave surface resistance is crucial for designing and optimizing devices with lowest energy losses, especially for high-temperature superconductors such as YBCO, which show great potential for many technological applications [9].…”
