Abstract
We have applied a de SQUID based microscope to stud! surface magnetization of a Ho single crystal at 77 K in parallel (up to 0.4 kA/m) and perpendicul ar (up to 0.1 kA/m) magnetic fields. Magnetization curves and the topograph ic maps of the magnetic field distribution near the polished surface (0001) of the crystals have been recorded with a spatial resolution better than 5 0 mu m. Qualitative evidence for ferromagnetic ordering at the (0001) surfa ce have been found.
