Abstract
Tl-2212 thin films were grown ex situ in a two step process on a varie ty of substrates, including ones with artificially introduced high ang le steps. Grain boundary weak links were formed on LaAlO3 substrates w ith steps and on bicrystal substrates and were employed in dc SQUIDs. The white noise level of the SQUIDs was 50 mu Phi(0)/root Hz at 77 K. A 12.5 GHz HEMT oscillator stabilized with a Tl-2212 resonator gave 8- 10 dB lower phase noise than using a gold resonator.
