Bednorz & Müller: superconductivity in copper oxides

Contribution grade

Chemistry & materials · Scoped scientific or research-capability contribution

Reference score85,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Reported superconducting behaviour in a barium–lanthanum–copper oxide system, opening the cuprate research program.

Scientific scope

Reported superconducting behaviour in a barium–lanthanum–copper oxide system, opening the cuprate research program. Scope limitation: High temperature is relative to earlier superconductors. This is not room-temperature superconductivity or a complete theory of cuprates.

Evidence

Assessment uses the catalogue-linked source evidence for the stated contribution. High temperature is relative to earlier superconductors. This is not room-temperature superconductivity or a complete theory of cuprates.
