A new family of superconductors emerged to rival the famous copper oxides. In 2019 researchers found superconductivity in nickelate materials. The discovery gave physicists a fresh system to probe an enduring mystery.
A new family
The class is fresh. Nickel-based compounds join the superconductors. Options expanded.
Cuprate cousins
Comparison is natural. Nickelates resemble the copper-oxide superconductors. Contrasts inform theory.
Testing theories
Utility is scientific. A new system checks ideas about high-temperature superconductivity. Understanding may grow.
Thin films
Fabrication is delicate. The materials are made as precise thin films. Technique matters.
Mechanism unclear
Mystery persists. Why they superconduct is unknown. Debate continues.
Active pursuit
Interest surged. Labs explore the family widely. Progress accumulates.
The bottom line
Nickelate superconductors, found in 2019, gave physicists a new system alongside the copper oxides. They offer a fresh way to test high-temperature superconductivity theories. The mechanism remains unclear.
