The table below shows some of the parameters of common superconductors. X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla. "BCS" means whether or not the superconductivity is explained within the BCS theory.
However, currently known high-temperature superconductors are brittle ceramics that are expensive to manufacture and not easily formed into wires or other useful shapes. [4] Therefore, the applications for HTS have been where it has some other intrinsic advantage, e.g. in: low thermal loss current leads for LTS devices (low thermal conductivity),
The current sharing temperature T cs is the temperature at which the current transported through the superconductor also starts to flow through the stabilizer. [ 5 ] [ 6 ] However, T cs is not the same as the quench temperature (or critical temperature) T c ; in the former case, there is partial loss of superconductivity, while in the latter ...
Over time, researchers have consistently encountered superconductivity at temperatures previously considered unexpected or impossible, challenging the notion that achieving superconductivity at room temperature was infeasible. [4] [5] The concept of "near-room temperature" transient effects has been a subject of discussion since the early 1950s.
Breakthrough would mark ‘holy grails of modern physics, unlocking major new developments in energy, transportation, healthcare, and communications’ – but it is a long way from being proven
High-temperature superconductors (HTS) become superconducting at more easily obtainable liquid nitrogen temperatures, which is much more economical than liquid helium that is typically used in low-temperature superconductors. HTS are ceramics, and are fragile relative to conventional metal alloy superconductors such as niobium-titanium.
