The table below shows some of the parameters of common superconductors. X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla. "BCS" means whether or not the superconductivity is explained within the BCS theory.
From about 1993, the highest-temperature superconductor known was a ceramic material consisting of mercury, barium, calcium, copper and oxygen (HgBa 2 Ca 2 Cu 3 O 8+δ) with T c = 133–138 K. [61] [62] In February 2008, an iron-based family of high-temperature superconductors was discovered.
All known high-T c superconductors are Type-II superconductors. In contrast to Type-I superconductors , which expel all magnetic fields due to the Meissner effect , Type-II superconductors allow magnetic fields to penetrate their interior in quantized units of flux, creating "holes" or "tubes" of normal metallic regions in the superconducting ...
Iron-based superconductors, including the oxypnictides. Magnesium diboride (MgB 2), whose critical temperature is 39K, [3] being the conventional superconductor with the highest known temperature. non-cuprate oxides such as BKBO. Palladates – palladium compounds. [4] [5] others, such as the "metallic" compounds Hg 3 NbF 6 and Hg 3 TaF

Last month, scientists confidently reported the discovery of a room temperature superconductor. Not so fast. Well, Seems Like LK-99 Isn’t a Room Temperature Superconductor After All
The most commonly used conventional superconductor in applications is a niobium-titanium alloy - this is a type-II superconductor with a superconducting critical temperature of 11 K. The highest critical temperature so far achieved in a conventional superconductor was 39 K (-234 °C) in magnesium diboride.
