FIG. 1.

(a) Schematic view of the SSM measurement. Pickup coil is scanned on a plane parallel to the sample surface. (b) Actual optical micrograph image of a circular pickup coil (diameter is ∼7.5 μm). (c) Details of the magnetic field near the superconducting pickup coil.

FIG. 2.

Geometry of the measurement.

Image of FIG. 3.
FIG. 3.

(a) is the black and white (binary) data of the pickup coil shape, (b) and (d) are the “naive” form factor, and (c) and (e) are the demagnetization-corrected form factor. The coordinates and are defined considering that the coil is reversed in the actual experiment. (d) and (e) are the three-dimensional plot.

Image of FIG. 4.
FIG. 4.

(a) Sample used for the measurement, a superconducting Pb honeycomb network, made of superconducting wires of width 1 μm. The pitch of the network is 7.4 μm. (b) Original image data of measured by SSM. (c) The processed data using the filter developed in this work. (d) The image where only the separation between sample and coil is corrected.
