High-temperature superconductivity is turning 25 years old.
In 1986, two IBM scientists---J. Georg Bednorz and K. Alex Muller---discovered superconductivity in an oxide material at -397 deg F. That temperature was 50 percent higher than the previous mark. Superconductivity was discovered in 1911 by Heike Kamerlingh Onnes, a Dutch physicist. Onnes discovered that superconductivity occurs when metals like tin and lead are cooled to absolute zero (-459.67 deg F).
Just a year after that discovery, Bednorz and Muller were awarded the Nobel Prize for Physics. Indeed, the high-temp superconductivity discovery had applications in measurement technology, electrotechnology and microelectronics.
Bednorz and Muller published "Possible High Tc Superconductivity in the Ba - La - Cu - O System"(2) was received by the peer-reviewed journal Zeitschrift fur Physik B on April 17, 1986.
