Abstract:YBa2Cu3O7-δ and Tl2Ba2CaCu2O8 thin films for microwave filters were synthesized by pulsed laser deposition and the two-step thalliation process. Substrate quality requirements and the relation of thin film morphology, microstructure with microwave surface resistance were discussed.
Keywords:YBCO superconducting films  Tl-2212 superconducting films  particles  microwave surface resistance Rs
