Superconductivity above 200 K discovered in superhydrides of calcium

Superconductivity above 200 K discovered in superhydrides of calcium Abstract Searching for superconductivity with T c near room temperature is of great interest both for fundamental science & many potential applications. Here we report the experimental discovery of superconductivity with maximum critical temperature ( T c ) above 210 K in calcium superhydrides, the new alkali earth hydrides experimentally showing superconductivity above 200 K in addition to sulfur hydride & rare-earth hydride ...
