Theory of Nb-Zr Alloy Superconductivity and First Experimental Demonstration for Superconducting Radio-Frequency Cavity Applications

Posted by klaurent Cornell

Kavli Affiliate: David A. Muller | First 5 Authors: Nathan S. Sitaraman, Zeming Sun, Ben Francis, Ajinkya C. Hire, Thomas Oseroff | Summary: Niobium-zirconium (Nb-Zr) alloy is an old superconductor that is a promising new candidate for superconducting radio-frequency (SRF) cavity applications. Using density-functional and Eliashberg theories, we show that addition of Zr to a […]
