      abstract     = {A scanning SQUID microscope based on high-temperature
                      superconductor (FITS) dc-SQUIDs was developed. An extremely
                      soft magnetic amorphous foil was used to guide the flux from
                      room temperature samples to the liquid-nitrogen-cooled SQUID
                      sensor and back. The flux guide passes through the pick-up
                      loop of the HTS SQUID, providing an improved coupling of
                      magnetic flux of the object to the SQUID. The device
                      measures the z component (direction perpendicular to the
                      sample surface) of the stray field of the sample, which is
                      rastered with submicron precision in the x-y direction by a
                      motorized computer-controlled scanning stage. A lateral
                      resolution better than 10 mum, with a field resolution of
                      about 0.6 nT Hz(-1/2) was achieved for the determination of
                      the position of the current carrying thin wires. The
                      presence of the soft magnetic foil did not significantly
                      increase the flux noise of the SQUID.},
