Abstract:Lateral Josephson junctions (LJJ) made of two superconducting Nb electrodes coupled by Cufilm are applied to quantify the stray magnetic field of Co-coated cantilevers used in Magnetic Force Microscopy (MFM). The interaction of the magnetic cantilever with LJJ is reflected in the electronic response of LJJ as well as in the phase shift of cantilever oscillations, simultaneously measured. The phenomenon is theorized and used to establish the spatial map of the stray field. Based on our findings, we suggest inte… Show more
