a Quantum sensing of nearby stray fields BF produced by generated from Fe3GeTe2 (FGT)148. Two-dimensional maps show the static stray field BF and the reconstructed magnetization 4 M of a suspended FGT slice, recorded at 6 K with a 142 G perpendicular magnetic field (Bext). b Visualization of Joule heating and current density, stray magnetic fields in a graphene-based device using spin defects in hBN147. c PL intensity distribution of a sensor array on the hBN flake168. d An image and a schematic of a microfluidic channel integrated into a gold stripline microwave waveguide for quantum sensing in solution229.
