Abstract
A broad spectrum around 50 G, possibly due to Josephson oscillations, has been observed in the superconductor Y1Ba2Cu3O7+x, using standard X- band EPR methodology. The spectrum has its tail extending to high fields and exhibiting complex oscillatory patterns such as expected from Josephson loops of sizes in the range of 0.65-0.81 μ. The EPR method can directly and nonabrasively detect small superconducting domains and Cu2+ inclusions in these materials. The detection of numerous Josephson junctions naturally present in such materials open up the possibilities for building new types of superconducting quantum interference devices.
