Superconductivity is a set of physical properties observed in certain materials where electrical resistance vanishes and magnetic flux fields are expelled from the material. Any material exhibiting these properties is a superconductor. Unlike an ordinary metallic conductor, whose resistance decreases gradually … See more There are many criteria by which superconductors are classified. The most common are: Response to a magnetic field A superconductor can be Type I, meaning it has a single See more Until 1986, physicists had believed that BCS theory forbade superconductivity at temperatures above about 30 K. In that year, See more Superconducting magnets are some of the most powerful electromagnets known. They are used in MRI/NMR machines, mass spectrometers, … See more • Andreev reflection – Scattering process at the normal-metal-superconductor interface • BCS theory – Microscopic theory of superconductivity • Bean's critical state model – Theoretical model for magnetic behaviour of some superconductors See more Several physical properties of superconductors vary from material to material, such as the critical temperature, the value of the … See more Superconductivity was discovered on April 8, 1911 by Heike Kamerlingh Onnes, who was studying the resistance of solid mercury at cryogenic temperatures using the recently produced liquid helium as a refrigerant. At the temperature of 4.2 K, he observed that the … See more • Heike Kamerlingh Onnes (1913), "for his investigations on the properties of matter at low temperatures which led, inter alia, to the production of liquid helium". • John Bardeen See more Websuperconductivity, complete disappearance of electrical resistance in various solids when they are cooled below a characteristic temperature.
