Microwave measurements of the high magnetic field vortex motion pinning parameters in Nb${}_3$Sn

Andrea Alimenti, Nicola Pompeo, Kostiantyn Torokhtii +4

The high frequency vortex motion in Nb${}_3$Sn was analyzed in this work up to 12 T. We used a dielectric loaded resonator tuned at 15 GHz to evaluate the surface impedance $Z$ of a…
