Change of strength of vortex pinning in YBCO due to BaZrO_3 inclusions

N. Pompeo, V. Galluzzi, R. Rogai +2

We probe the short-range pinning properties with the application of microwave currents at very high driving frequencies (47.7 GHz) on YBa${}_2$Cu${}_3$O${}_{7-\delta }$ films with and without…
