ABSTRACT: 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.
