Imaging the Meissner effect in hydride superconductors using quantum sensors
Researchers have developed a new technique for imaging the Meissner effect in hydride superconductors using quantum sensors. By applying pressure to the superconducting material and using a shallow layer of nitrogen-vacancy colour centres implanted within a diamond anvil cell, the researchers were able to perform local magnetometry with sub-micron spatial resolution at high pressures. They applied this technique to characterize a hydride superconductor called CeH9 and observed the dual signatures of superconductivity: diamagnetism characteristic of the Meissner effect and a sharp drop in resistance to near zero. The researchers were also able to directly image the geometry of superconducting regions and found inhomogeneities at the micron scale. This work opens up new possibilities for studying superconducting materials at high pressures and optimizing their synthesis.
