Abstract
A surface modification of diamond with manganese powder was attempted to make a magnetic functional surface for handling diamond. Manganese carbide, Mn 7 C 3 , was formed on diamond (110) by near-infrared radiation heating, resulting in a layered material with suppressing formation of Mn 5 C 2 . Investigated by a Hall-effect sensor, the magnetic flux density on the modified diamond surface showed ferromagnetic properties.
