Abstract
The construction of magnetic force microscope (MFM) operating in air at room temperature has been explained. The magnetic domain in the Co-Pd multilayer film(Co (4.0 Å)/Pd (13.2 Å)×17 layers) was studied with our home-made MFM. The MFM image obtained under an ambient condition in the earth's magnetic field showed a natural magnetic domain structure. The lines of the image seems to be the domain walls with the thickness of about 500-1000 A. The contrast of magnetic structure is dominant compared to that of the topographic structure when the magnetic tip is at the position about 1000 A away from the magnetic sample surface. The finest structure observed in our MFM images is of order about 500-1000 Å.
