High power RF device performance decreases as operation temperature increases (e.g. decreasing electron mobility affects cut-off frequencies and degrades device reliability). Therefore determination of device temperature is a key issue for device top

During the last five years, the surface resistance R s (10 GHs, 77 K) of YBCO thin films has decreased from a value of about 10 to 20 milliohms-i.e. the same as cooled pure copper or as bulk YBCO-down to values lower than 200 micro-ohms, close to the

In an attempt to pattern microbridges in a superconducting line by focused ion beam milling, we have obtained a very high critical current density: 6 × 108 A/cm2 at 77 K. Direct focused ion milling leads to microbridge structures as narrow as 200 nm

We report modulated microwave absorption studies of a superconducting square loop closed by a josephson junction. We show that the width of the absorption peak is due to quantum fluctuations at low temperature (
