'Superconducting dome' hints at high-temperature superconductivity in thin nickelate films‎

Superconductivity is a quantum state of matter characterized by an electrical resistance of zero and the expulsion of magnetic fields at low temperatures below a critical point. Superconductors, materials in which this state occurs, have proved to be highly advantageous for the development of various technologies, including medical imaging devices, particle accelerators and quantum computers.
