dc.description.abstractWe report the quantum calibration of a magnetic force microscope (MFM) by measuring the two-dimensional magnetic stray-field distribution of the MFM tip using a single nitrogen vacancy (NV) center in diamond. From the measured stray-field distribution and the mechanical properties of the cantilever a calibration function is derived allowing to convert MFM images to quantum calibrated stray-field maps. This approach overcomes limitations of priorMFM calibration schemes and allows quantum calibrated nanoscale stray-field measurements in a field range inaccessible to scanning NV magnetometry. Quantum calibrated measurements of a stray-field reference sample allow its use as a transfer standard, opening the road towards fast and easily accessible quantum traceable calibrations of virtually any MFM.

dc.description.sponsorshipThe work was co-funded by the Deutsche Forschungsgemeinschaft under Germany's Excellence Strategy -EXC2123 QuantumFrontiers -Grant No. 390837967. The work was supported by European Research Council, European Union's Horizon 2020 research project ASTERIQS, Baden-Wurttemberg Stiftung and Bundesministerium fur Bildung und Forschung. B.S. acknowledges support from TUBITAK2214-A -International Research Fellowship Programme for PhD Students-Grant No. 1059B141800226. We thank C. Krien for preparing the Co/Pt multilayer sample. Y.L. and B.S. developed the experimental protocol for the tip calibration and performed the MFM and NV experiments at Ulm. Y.L. built the MFM-confocal setup and provided the tip-field data. B.S. carried out the numerical data analysis to derive the quantum calibration function and the field distributions including uncertainty analysis. B.S., V.N., and S.S. discussed the numerical analysis and the calibration procedures. V.N. provided and characterized the Co/Pt sample. M.L.M. provided the diamond SIL sample. C.O. carried out diamond layer overgrowth on the planar surface. J.L. carried out NV center implantation. F.J., H.W.S., and O.O. initiated and coordinated the project. B.S., Y.L., S.S., V.N., F.J., and H.W.S. jointly discussed all data and wrote the manuscript.
