Some positive steps were made in this direction through the use of niobium-based alloys. In 1973 the alloy Nb3Ge was found to have a Tc = 23 K, which remained the highest attainable critical temperature until 1986. In 1986 two IBM scientists in Zurich, the German, Johannes Georg Bednorz and the Swiss, Karl Alex Muller found that a ceramic oxide based on lanthanum, barium and copper (of stoichiometry...

Since 1911, scientists have been searching for materials that superconduct at higher temperatures, and more than 6000 superconductors are now known. Until 1986, however, the record value of Tc was only 23.2 K (for the compound Nb3Ge). The situation changed dramatically in 1986 when K. Alex Muller and J. Georg Bednorz of the IBM Zurich Research Laboratory reported a Tc of 35 K for the non-stoichiometric barium lanthanum copper oxide BavLa2-.vCu04, where x has a... 

Until 1986 many experiments were carried out using metals and alloys. However, in 1986 Georg Bednorz and Alex Muller, two researchers of the IBM laboratory in Ruschlikon near Zurich, published an article in the Zeitschrift fur Physik in which they announced that they had made a superconducting ceramic material. It turned out to be a compound made of barium, copper, lanthanum and oxygen, which became superconducting at 35 K. They were awarded the Nobel prize for this discovery. After this, superconductors developed rapidly, at least as far as critical temperature is concerned. 

In 1986, IBM researchers K. Alex Muller and Georg Bednorz paved the path to superconductivity at slightly higher temperatures using a ceramic alloy as a medium. Shortly thereafter, a team led by University of Houston physicist Paul Chu created a ceramic capable of superconductivity at temperatures high enough to encourage true commercialization.

Bednorz, Johannes Georg (born 1950) and Karl Alexander Muller (born 1927) were scientists at the IBM research laboratory in Zurich, Switzerland, where they discovered the phenomenon of high-temperature superconductivity. They were both awarded the Nobel Prize for Physics in 1987. They began working together in 1982. 

In January 1986, K. Alex Muller and J. Georg Bednorz, scientists at an IBM laboratory in Switzerland, discovered that a barium—Ianthanum-liquid helium. This discovery provoked a flurry of activity that quickly resulted in a substance that became superconducting at 90 K. LaBa2CujO was then... 

The first non-metallic superconductor was found in 1964. In 1986, George Bednorz and Alex Muller of IBM, Switzerland discovered that certain copper oxide materials become superconducting at 30K. Similar materials with high T values were reported soon after. The compound is a mixed oxide with a formula La(2-x) (4-y) where x is 0.15 - 0.20 and y is a very small quantity. This compound... 

Because of the numerous bogus reports of high-temperature superconductivity before 1986, Karl Muller and J. Georg Bednorz were extremely cautious in revealing their discovery, and their tentative announcement was so modest that their paper initially aroused little interest.
