Abstract

We measured the microwave surface resistance R_s of superconducting YBa₂Cu₃O_7-x (YBCO) films on buffered polycrystalline alumina and Ni-based alloy substrates using a parallel-plate resonator technique. We observed a strong correlation between the low-power R_s and the in-plane mosaic spread of the YBCO films. A 0.4-μm-thick YBCO film with an in-plane mosaic spread of 6.6° (7°) on a buffered polycrystalline Ni-based alloy (buffered polycrystalline alumina) substrate showed an R_s of 0.51 mΩ (1.89 mΩ) at 76 K and 0.17 mΩ (0.21 mΩ) at 4 K.
