摘要：

The microwave properties of high-J(c) (similar to 10(6) A cm(-)2()) c-axis Y1Ba2Cu3O7 thin films on MgO(100) substrates were investigated as a function of the film microstructure. Measurements at 77 K, using a sapphire dielectric resonator operated in the TE(011) mode, show that the microwave surface resistance, R(s), at 10 GHz increases from 0.8 m Ohm for very smooth films to 3-4 m Ohm for films with large scale microstructural defects such as outgrowths and holes or pits. The unloaded quality factor Q(u) decreases from about 96,000 to below 50,000.
