Abstract
PURPOSE:To contrive a film forming speed by heating and melting a magnetic material essentially consisting of iron and directing the vapor flow onto a nonmagnetic substrate, then directing material flow which is mainly the fast neutron particle flow essentially consisting of nitrogen components toward the nonmagnetic substrate, thereby providing the thin magnetic film of an iron nitride system on the substrate. CONSTITUTION:The nonmagnetic substrate 2 is held on a substrate holder 1. Iron 9 heated and melted by an electron beam 8 is evaporated to vapor flow 11 which is directed onto the substrate. Gaseous nitrogen is introduced from a gas introducing port 7 simultaneously therewith and the fast neutron particle flow 12 is generated by operating an ion gun 6 provided with an ion neutralizing means 3 in an ion gun drawing out port. This particle flow is directed toward the nonmagnetic substrate. The ion neutralizing means heats a filament 4 to release thermions and directs the thermions toward a counter electrode 5 so as to cross the beam. The beam is thereby made into the fast neutron particle flow 12. The average energy of the fast neutron flow is determined by the acceleration voltage in the ion gun 6. The film forming speed is thereby increased and the magnetic recording medium is produced.
