Imaging the Meissner effect and flux trapping of superconductors under high pressure using N-<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>V</mml:mi></mml:math> centers
Understanding how superconductors behave under intense pressure is essential for the quest to discover materials with higher critical temperatures. However, magnetic measurements inside a diamond anvil cell remain technically challenging, contributing to controversies in high-pressure superconductivity. This study uses nitrogen-vacancy centers in diamond to visualize the Meissner effect and flux trapping in situ in a diamond anvil cell. The technique reveals spatial inhomogeneities in samples and provides micrometer-scale magnetic maps across the superconducting transition.
