A nickel-based compound has demonstrated superconductivity at a temperature of 80 kelvin under high pressure, bridging the gap between other nickelates and copper-based superconductors. This discovery opens up new possibilities for finding technologically useful superconducting materials.
Researchers have discovered that the resistivity of optimally superconducting (Nd,Sr)NiO2, an infinite-layer nickelate, exhibits a linear-in-temperature behavior, similar to high-temperature cuprate superconductors. This finding suggests a common underlying mechanism for superconductivity in both material classes. The study provides insights into the electronic properties of nickelates and their potential for high-temperature superconductivity.
Researchers at Cornell have used advanced electron microscopy techniques to uncover an unexpected atomic structure within a newly discovered class of nickel-based superconductors, providing a blueprint for how more functional versions might be engineered in the future. The study shows that superconductivity may not be reliant on the thin-film geometry, meaning that creation of superconducting bulk crystals theoretically should be possible. The discovery is encouraging for the field because it shows that superconductivity is occurring in the nickelate film itself, not at the atomic interface where the film and substrate meet.
