Common tools of neighborhood magnetic imaging reveal both a excessive spatial answer and comparatively bad box sensitivity (MFM, Lorentz microscopy), or a comparatively excessive box sensitivity yet constrained spatial answer (scanning SQUID microscopy). because the magnetic box of a nanoparticle or nanostructure decays quickly with distance from the constitution, the feasible spatial answer is eventually constrained by means of the probe-sample separation. This thesis offers a singular technique for fabricating the smallest superconducting quantum interference equipment (SQUID) that is living at the apex of a truly sharp tip. The nanoSQUID-on-tip screens a attribute measurement all the way down to a hundred nm and a box sensitivity of 10^-3 Gauss/Hz^(1/2). A scanning SQUID microsope was once developed via gluing the nanoSQUID-on-tip to a quartz tuning-fork. This enabled the nanoSQUID to be scanned inside of nanometers of the pattern floor, offering simultaneous photographs of pattern topography and the magnetic box distribution. This microscope represents an important development over the present scanning SQUID concepts and is predicted for you to snapshot the spin of a unmarried electron.
