The Seventh International Symposium on Superconductivity brought together researchers at the forefront of all fields such as physics, chemistry, materials, production engineering, and electronic and electrical engineering, once again underlining the interdisciplinary nature of high-temperature superconductivity. Speakers shared their latest findings in the fundamental physics and chemistry; superconductors in the form of individual devices and systems. This comprehensive volume will prove indispensable for all who are involved in high-temperature superconductivity research.
