Shockwave-Loading-Induced Enhancement of T c in Superconducting Bi2Sr2CaCu2O8+δ

Abstract We report a shockwave method for altering the properties of the superconductor material Bi2Sr2CaCu2O8+δ (Bi2212). We find that the superconducting transition temperature (T c) increases from 84 K for the pristine sample to 94 K for the sample treated at a temperature and pressure of ~1200 K...
