Some researchers hope the new materials will help solve the mystery of cuprate high temperature superconductors (discovered in 1986) “It’s possible that these materials will provide a cleaner system ...

The discovery that compounds known as iron pnictides can superconduct at 50 degrees above absolute zero has reignited physicists' quest for better high-temperature superconductors, and may offer clues ...

A new class of high-temperature superconductors, discovered earlier this year, behaves very differently than previously known copper-oxygen superconductors do. Instead, the new materials seem to ...

Superconductors can now be synthesized at much lower temperatures and with shorter reaction times. The recent discovery that certain iron-based, magnetic materials called oxypnictides can conduct ...
