Investigations in Superconductors of Small Size by Electron Paramagnetic Resonance Technique
The possibility to investigate the non resonant AC induced microwave dissipation in superconductors of small size down to nanoscale by means of a conventional electron paramagnetic resonance (EPR) spectrometer is discussed. This contact free method provides a direct access to the Josephson vortex (JV) system in highly anisotropic superconductors like Bi2Sr2CaCu2O8+δ . The extremely high signal intensities observed in macroscopic samples promise sizeable signals even for very small samples. This allows investigating the effect of reduced dimensions on the properties of the vortex system, like for example the pinning of Josephson vortices by Abricosov vortices or the memory effect induced by field cooling, when reducing the sample thickness to a few superconducting layers.
