  text: Scanning nanoscale superconducting quantum interference devices (nanoSQUIDs)
    are of growing interest for highly sensitive quantitative imaging of magnetic,
    spintronic, and transport properties of low-dimensional systems. Utilizing specifically
    designed grooved quartz capillaries pulled into a sharp pipette, we have fabricated
    the smallest SQUID-on-tip (SOT) devices with effective diameters down to 39 nm.
    Integration of a resistive shunt in close proximity to the pipette apex combined
    with self-aligned deposition of In and Sn, has resulted in SOTs with a flux noise
    of 42 nΦ0 Hz−1/2, yielding a record low spin noise of 0.29 μB Hz−1/2. In addition,
    the new SOTs function at sub-Kelvin temperatures and in high magnetic fields of
    over 2.5 T. Integrating the SOTs into a scanning probe microscope allowed us to
    image the stray field of a single Fe3O4 nanocube at 300 mK. Our results show that
    the easy magnetization axis direction undergoes a transition from the 〈111〉 direction
    at room temperature to an in-plane orientation, which could be attributed to the
    Verwey phase transition in Fe3O4.
