SYNTHESIS AND MICROWAVE CHARACTERIZATION OF DC SPUTTERED TL-BA-CA-CU-O THIN-FILMS

Abstract:

Single and double sided superconducting Tl-Ba-Ca-Cu-O thin films (2 μm thick) have been prepared on MgO (100) and LaA1O3 (100) substrates by DC sputtering followed by a two step anneal process. Films produced have Tc between 90 and 110 K with transport critical current densities typically 103 to 105 A cm-2. Surface resistance (Rs) measurements at 50 GHz and 60 GHz over the temperature range 18-200 K have been made using a TE01 mode cavity end wall replacement technique giving Rs of 380 mΩ at ...
