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 first practical application of superconductivity was developed in 1954 with Dudley Allen Buck's invention of the cryotron. [22] Two superconductors with greatly different values of the critical magnetic field are combined to produce a fast, simple switch for computer elements.
ReBCO superconductors have the potential to sustain stronger magnetic fields than other superconductor materials. Due to their high critical temperature and critical magnetic field, this class of materials are proposed for use in technical applications where conventional low-temperature superconductors do not suffice.
Often superconducting computing is applied to quantum computing, with an important application known as superconducting quantum computing. Superconducting digital logic circuits use single flux quanta (SFQ), also known as magnetic flux quanta, to encode, process, and transport data. SFQ circuits are made up of active Josephson junctions and ...
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.
Metal alloy superconductors can also exhibit type-II behavior (e.g., niobium–titanium, one of the most common superconductors in applied superconductivity), as well as intermetallic compounds like niobium–tin. Other type-II examples are the cuprate-perovskite ceramic materials which have achieved the highest superconducting critical ...
The motivation for using superconductors in RF cavities is not to achieve a net power saving, but rather to increase the quality of the particle beam being accelerated. Though superconductors have little AC electrical resistance, the little power they do dissipate is radiated at very low temperatures, typically in a liquid helium bath at 1.6 K ...
According to physicist Philip Warren Anderson, the use of the term "condensed matter" to designate a field of study was coined by him and Volker Heine, when they changed the name of their group at the Cavendish Laboratories, Cambridge, from Solid state theory to Theory of Condensed Matter in 1967, [10] as they felt it better included their interest in liquids, nuclear matter, and so on.
