Magnetic resonance imaging (MRI) has revolutionized biomedical science by providing non-invasive, three-dimensional biological imaging [1]. However, spatial resolution in conventional MRI systems is limited to tens of microns [2], which is insufficient for imaging on molecular and atomic scales. Here we demonstrate an MRI technique that provides(More)

Microscopic studies of superconductors and their vortices play a pivotal role in understanding the mechanisms underlying superconductivity. Local measurements of penetration depths or magnetic stray fields enable access to fundamental aspects such as nanoscale variations in superfluid densities or the order parameter symmetry of superconductors.
