c-axis single domain YBCO crystals have been grown by using the seeded melt
growth (SMG) method. Surface resistance has been measured at 12.95 GHz and
77 K in magnetic fields up to 1.5 T. The Pippard scaling behavior has been
found in the well-oxygenated crystal indicating the high-quality of the si
ngle domain YBCO and similar loss mechanism compared to conventional superc
onductors.
