High-temperature superconductivity (high-T c or HTS) is superconductivity in materials with a critical temperature (the temperature below which the material behaves as a superconductor) above 77 K (−196.2 °C; −321.1 °F), the boiling point of liquid nitrogen. [1]

2024年11月4日 · High-temperature superconductors (HTSs) can support currents and magnetic fields at least an order of magnitude higher than those available from LTSs and non-superconducting conventional...

2021年5月28日 · Superconductors with high superconducting transition temperatures (Tc) have unusual properties that cannot be explained by conventional Fermi liquid theory or the Bardeen–Cooper–Schrieffer...

2025年2月18日 · A new family of superconductors is exciting physicists. Compounds containing nickel have been shown to carry electricity without resistance at the relatively high temperature of 45 kelvin (–228 ...

2022年9月21日 · A new experiment led by the condensed matter physicist Séamus Davis at the University of Oxford all but settles the origin of high-temperature superconductivity, a puzzle Davis has worked on for 25 years.

2024年5月15日 · Our research may pave the way for finding high- superconductors in ternary hydrides. The pursuit of high-$ {T}_ {c}$ superconductors has remained a long-thought goal within the field of condensed-matter physics and material science.

2025年2月2日 · The high-T c superconductors are type II superconductors. They exhibit zero resistance, strong diamagnetism , the Meissner effect , magnetic flux quantization , the Josephson effects, an electromagnetic penetration depth, an energy gap for the superconducting electrons, and the characteristic temperature dependencies of the specific heat and ...

High-temperature superconductors have substantially higher T c transition temperatures than normal superconductors. The temperatures can reach 203 K, which is around 180 K higher than the temperature range of regular superconductors and already inside the temperature range of naturally occurring temperatures on the earth's surface [67] .

2025年2月4日 · Researchers have made a significant step in the study of a new class of high-temperature superconductors: creating superconductors that work at room pressure. That advance lays the groundwork for deeper exploration of these materials, bringing us closer to real-world applications such as lossless power grids and advanced quantum technologies.

2025年2月6日 · In a superconductor, pairs of electrons are coaxed together at low temperature into a collective state that flows without resistance. Lattice vibrations provide the nudging in conventional superconductors; in the high-T c cuprates, antiferromagnetic fluctuations do the job.Now Xiao-Gang Wen of MIT and his collaborators have identified conditions under which …
