“…Numerous techniques of superconductor film characterization use a magnetic field as a means to display sources of residual losses. A static magnetic field applied to the surface of an HTSC film placed in a resonator permits one to determine physical mechanisms of microwave residual losses [7]. Other methods such as Hall sensors, magnetooptic films and magnetic force microscopy [8][9][10] have been developed to obtain MFMs.…”

Scanning SQUID microscopy has been extended to record current-induced magnetic field maps of superconductor topologies based on YBCO film structures. The technique described can be used as a powerful tool for the diagnostics of superconductor integrated circuits and highly sensitive bolometers. This kind of diagnostics predicts the degree of integration which can be achieved at the modern level of HTSC microelectronics technology. One would expect an overall yield of 100-element chips at a level of in the production of superconducting YBCO/MgO bolometers.

The RF and microwave response of YBa2Cu307-S films on Ba,Srj-,TiOs/MgO substrates was investigated in an external static magnetic field. Films with a varying thickness, orientation and type of structure were studied in order to understand the mechanisms of RF and microwave residual losses. The measurements of surface resistance (R) as a function of the film t h i c h s s and static ( H ) and RF (H-) magnetic field are discussed. Analysis of theoretical and experimental R(H) dependences has shown that residual RF and microwave losses occur in a static magnetic field on Josephson junctions formed at grain boundaries and at microblock boundaries with trapped Abrikosov vortices and on Abrikosov vortices themselves, and are also caused by non-superconductive inclusions.
