The ceramic materials used to make superconductors are a class of materials called perovskites.
Ceramic superconductors temperature.
They are then called low temperature superconductors.
Better superconductors from ceramic copper oxides.
On the other hand metallic superconductors usually work below 200 c.
This superconductor has a critical transition temperature around 90k well above liquid nitrogen s 77k temperature.
Between 1911 and 1986 a variety of materials were found to be superconducting some of which are indicated on fig.
Atoms stand in for electrons in system for probing high temperature superconductors.
The principle goals of this program were 1 to demonstrate fabrication of high temperature ceramic superconductors via a sol gel method that can operate at or above 90k with appropriate current.
The superconductor we will be experimenting with is an yttrium y barium ba and copper cu composition.
All superconducting materials known at ordinary pressures currently work far below ambient temperatures and therefore require cooling.
Chemical formula is yba2cu3o7.
Riccardo comin seeks to elucidate the microscopic physics of high temperature superconducting devices to advance their technological applications.
