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.

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.
9.9: Superconductivity - Physics LibreTexts
When the temperature decreases below a critical value for many materials, their electrical resistivity drops to zero, and the materials become superconductors. Watch this NOVA video excerpt, Making Stuff Colder, as an introduction to the topic of …

2024年2月11日 · Superconductivity is a quantum mechanical phenomenon where a material exhibits zero electrical resistance and expels magnetic fields when cooled below a characteristic critical temperature (T c). Superconductors are the materials that exhibit this phenomenon.
Superconductivity - Harvard University
The state of the system is parameterized by carrier concentration (doping), temperature, and magnetic field. Two known phases are antiferromagnetism (at low doping) and superconductivity; little is known about the electronic structure throughout the rest of phase space.
rst one Hg was discovered by Onnes in 1911. It becomes superconducting for T < 4:2 K. Clearly this superconducting state must be fundamentally di erent than the "normal" metallic state. I.e., the superconducting state must be a di erent phase, separated by …
