Abstract
The microwave power dependence of high quality Tl(Ba,Sr)/sub 2/Ca/sub 2/Cu/sub 3/O/sub y/ thin films grown on 1'' diameter LSAT substrates using the Amorphous Phase Epitaxy method has been investigated in this paper. We have performed surface resistance (R/sub S/) measurements of Tl-1223 thin films on LSAT using the Hakki-Coleman sapphire dielectric resonator technique in the temperature range 15-94 K. High accuracy in measurements was achieved by using the multi-frequency Transmission Mode Q-Factor Technique. The Tl-1223 films exhibited low surface resistance comparable to YBCO films. When RF power levels were increased the onset of nonlinearity was observed at 0 dBm for all measured temperatures (17, 50, 70 and 84 K).
