Abstract: Transition metal doped II–V nitride material films exhibit ferromagnetic properties at or above room temperature. A III–V nitride material film may be doped with a transition metal film in-situ during metal-organic chemical vapor deposition and/or by solid-state diffusion processes. Doping of the III–V nitride material films may proceed in the absence of hydrogen and/or in the presence of nitrogen. In some embodiments, transition metal-doped III–V nitride material films comprise carbon concentrations of at least 1017 atoms per cubic centimeter.

Abstract: A method of producing high performance permanent magnets is disclosed in which particles of a master alloy consisting of Fe.sub.2 B having a maximum particle size of 50 microns is admixed with Fe powder and particles of a rare earth capable of combining with Fe and B to form a tetragonal compound of Fe.sub.14 R.sub.2 B type. The admixture is compacted and a magnetic material is formed of the master alloy, Fe powder and rate earth particles which includes a major phase of at least one intermetallic compound of the Fe-R-B type having a crystal structure of the substantially tetragonal system and while the particle size of the crystal structure is controlled by sintering the compacted admixture at a temperature of about 700.degree. C. to 1000.degree. C. for from a fraction of an hour to 36 hours. The magnetic material is then annealed at a temperature of about 550.degree. C. to 650.degree. C. for a fraction of an hour to 2 hours.
