Chemical Name: Magnesium boride (MgB₂)

Superconductivity Situation:

Magnesium diboride has been known to scientists for approximately 50 years, however, no one had ever investigated superconductivity in the material – whether it could conduct electrical current perfectly, without resistance, when cooled to
temperatures near absolute zero.

That all changed in January 2001 when Jun Akimitsu of Aoyama Gakuin University in Tokyo announced he and his research team had discovered that magnesium diboride becomes superconducting at 39 Kelvin (-389 F), nearly twice the temperature of
current intermetallic superconductors. The announcement had experimentalists around the world rushing to duplicate and confirm the Japanese findings.
