Iron boride is a newly discovered superhard material and superconducting material, which has been successfully synthesized in the laboratory by Huiyang Rang of Bayreuth University and others. It is the first superconductor designed by a computer and then prepared according to the calculation results.

The superconductor was prepared according to the calculation results. Superconductor,

Refers to a conductor that can exhibit zero resistance below a certain temperature. Zero resistance and complete diamagnetism are two important characteristics of superconductors. The temperature at which the resistance of a superconductor turns to zero is called the superconducting critical temperature. According to this, superconducting materials can be divided into low-temperature superconductors and high-temperature superconductors. The "high temperature" here is relative to absolute zero, which is actually much lower than the freezing point of 0°C. Scientists have been seeking to increase the critical temperature of superconducting materials. The current record of the highest temperature of high-temperature superconductors is the Mark Planck Institute 203K (-70° C). Because of the zero resistance, superconducting materials have many applications in generating strong magnetic fields, such as MRI and magnetic resonance imaging.
