Surface Impedance Measurements on Nb $_{3}$ Sn in High Magnetic Fields

Nb3 Sn is a superconductor of great relevance for perspective radiofrequency (RF) applications. We present for the first time surface impedance (Z9) measurements at 15 GHz and low-RF field amplitude on Nb3 Sn in high magnetic fields up to 12 T, with the aim of increasing the knowledge of Nb3 Sn behavior in such conditions. Z9 is a fundamental material parameter that directly gives useful informati...
