Microwave loss tangents of various perovskite-related substrates have been measured at 77 K by inserting them in a 5 GHz microstrip resonator structure. Results include LaAlO3 (1 × 10−5, NdGaO3 (3 × 10−4 ), and CaNdAlO4 (1 × −4). High qualit

We present a set of experiments which show that three dielectric processing variables in particular affect the performance of superconducting microwave devices: processing time and temperature, moisture content of the dielectric material, and surface

We have measured the surface resistance Rs of laser‐deposited Tl2Ba2CaCu2O8 thin films on LaAlO3 substrates. After correcting for leakage of radiation through the films, we find that the normalized surface resistance Rs/RN (with RN the normal‐sta

We have fabricated and tested a 1 ns microstrip delay line using thin films of Tl2Ba2CaCu2O8. We determined the loss in the delay line by weakly coupling at the input and output and measuring the width of the fundamental resonance at 461 MHz. At 15 K

Measurements are presented which show the effect of proton irradiation on the irreversibility line and critical current in Tl2 CaBa2Cu2O8 thin films. These data show that the irreversibility line is dependent on the defect structure and that the pinn

We report results on several passive microwave devices fabricated and tested using epitaxial thin films of Tl2CaBa2Cu2O8 grown on LaAlO3. We report microstrip resonators with unloaded Q’s of 15,000 at 80K and 4.83 GHz, and 1440 at 80K and 33 GHz. W

We report measurements of microwave surface resistance in Tl‐based superconductor thin films made by laser ablation followed by a post‐deposition thermal process. The films were measured by using cavity methods. The data at 9.5 and 148 GHz indica

A chemical deposition process for the preparation of superconducting thin films of Tl2CaBa2Cu2O8 (2122) and Tl2Ca2Ba2Cu3O10 (2223) has been developed. Oriented, superconducting 2122 and 2223 thin films have been successfully fabricated on single‐cr
