  • Superconductivity - Wikipedia
    Superconductivity is a set of physical properties observed in superconductors: materials where electrical resistance vanishes and magnetic fields are expelled from the material
  • Superconductivity | Physics, Properties, Applications | Britannica
    Superconductivity, complete disappearance of electrical resistance in various solids when they are cooled below a characteristic temperature This temperature, called the transition temperature, varies for different materials but generally is below 20 K (−253 °C)
  • DOE Explains. . . Superconductivity - Department of Energy
    Superconductivity is the property of certain materials to conduct direct current (DC) electricity without energy loss when they are cooled below a critical temperature (referred to as T c) These materials also expel magnetic fields as they transition to the superconducting state
  • Superconductivity – Home | CERN
    In 1911, while studying the properties of matter at very low temperature, the Dutch physicist Heike Kamerlingh Onnes and his team discovered that the electrical resistance of mercury goes to zero below 4 2 K (-269°C) This was the very first observation of the phenomenon of superconductivity
