A surface modification of diamond with manganese powder was attempted to make a magnetic functional surface for handling diamond. Manganese carbide, Mn₇C₃, was formed on diamond (110) by near-infrared radiation heating, resulting in a layered material with suppressing formation of Mn₅C₂. Investigated by a Hall-effect sensor, the magnetic flux density on the modified diamond surface showed ferromagnetic properties.
