A new age of superconductors may be about to beginn: In the 1980s, many superconducting materials (called cuprates) were based on copper. Then, nickelates were discovered — a new kind of superconducting materials based on nickel. But now, scientists from Austria and Japan have shown: There is a ‘Goldilocks zone’ of superconductivity which can neither be reached with cuprates nor with nickelates. Instead, palladium-based materials (‘palladates’) could be the solution.
