"Optimal Superconductivity Achieved with Linear-in-Temperature Resistivity in (Nd,Sr)NiO2"

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.
