  A novel scanning probe technique is presented: Scanning microSQUID Force
microscopy (SSFM). The instrument features independent topographic and magnetic
imaging. The SSFM operates in a dilution refrigerator in cryogenic vacuum.
Sample and probe can be cooled to 0.45 K. The probe consists of a microSQUID
placed at the edge of a silicon chip attached to a quartz tuning fork. A
topographic vertical resolution of 0.02 micrometer is demonstrated and magnetic
flux as weak as $10^{-3} \Phi_{0}$ is resolved with a 1 micrometer diameter
microSQUID loop.
