Wide-field quantitative magnetic imaging of superconducting vortices using perfectly aligned quantum sensors
نویسندگان
چکیده
Various techniques have been applied to visualize superconducting vortices, providing clues their electromagnetic response. Here, we present a wide-field, quantitative imaging of the stray field vortices in thin film using perfectly aligned diamond quantum sensors. Our analysis, which mitigates influence sensor inhomogeneities, visualizes magnetic flux single YBa2Cu3O7−δ with an accuracy ±10%. The obtained vortex shape is consistent theoretical model, and penetration depth its temperature dependence agree previous studies, proving our technique's broad applicability. This wide-field imaging, principle works even under extreme conditions, allows characterization various superconductors.

Current Imaging using Magnetic Field Sensors
As process technologies of integrated circuits become more complex and the industry moves toward advanced packaging like flip-chip and stacked die, present tools and techniques are having increasing difficulty in meeting failure analysis needs [1]. With gate sizes approaching 65 nm, “killer defects” may only be a few nanometers in size. In some cases, the defects are nonvisible, i.e. there is n...
متن کاملWide-field Magnetic Field Imaging with Nitrogen
The nitrogen vacancy center (NV) is a promising single spin system in diamond with optical polarization, readout and optically detected magnetic resonances (ODMR). The NV has been shown to be a sensitive magnetometer at room temperature. In particular, owing to their small size, NV centers in nanocrystals (nanodiamonds) offer magnetic field imaging with high spatial resolution. Competitive magn...

A spectrometer incorporating a high transition temperature dc superconducting quantum interference device ~SQUID! is used to obtain nuclear magnetic resonance signals from protons in mineral oil at room temperature in fields up to 3 mT. The spatial separation between the SQUID magnetometer at 77 K and the sample at room temperature is less than 1 mm. At 2 mT, the signal is easily resolved in a ...
