Spatially-resolved study of the Meissner effect in superconductors using NV-centers-in-diamond optical magnetometry
Spatially-resolved study of the Meissner effect in superconductors using NV-centers-in-diamond optical magnetometry
Non-invasive magnetic field sensing using optically - detected magnetic resonance of nitrogen-vacancy (NV) centers in diamond was used to study spatial distribution of the magnetic induction upon penetration and expulsion of weak magnetic fields in several representative superconductors. Vector magnetic fields were measured on the surface of conventional, Pb and …
