Our research purpose is to read the spin orientation of single-atom magnets by force. The magnetic exchange force between Ho atoms (4f atom) and Co atoms (3d atom) was measured using dynamic force microscopy. We found that the magnetic exchange force between a Ho atom and a Co tip increases above the point contact and decreases below the point contact, as the tip approaches a Ho atom.
