Superconducting coupling between two regions separated by a one micron wide ferromagnetic compound has been proved by an international team. This macroscopic quantum effect, known as Josephson effect, ...

In 2020, researchers reported that they had created a room-temperature superconductor. That paper has now been retracted. Editor’s Note: On September 26, 2022, the journal Nature retracted the paper ...

Superconductors are materials that can conduct electricity with zero resistance when they are cooled below a certain critical temperature. They have applications in several fields, including magnetic ...

The pursuit of room-temperature superconductivity has long been a holy grail in the field of condensed matter physics because it could revolutionize all electricity based technologies and in ...
