A novel microwave technique for detection of superconductivity

摘要

A new technique for detection of superconductivity which is based upon microwave resistivity is described. This method is similar in both its implementation and execution to the technique of electron‐spin resonance, and, as a consequence, exhibits high sensitivity. An additional benefit of this method is the fact that metal‐insulator phase transitions of materials are recorded only if they have a magnetic field dependence.
