description The inherently high magnetic anisotropy and nanoscale grain size in a Sm 5 Co 19 compound result in an intrinsic coercivity far higher than those of known Sm-Co compounds prior to orientation treatment. The combination of ultrahigh intrinsic coercivity, high Curie temperature and low coercivity temperature coefficient of nanocrystalline Sm 5 Co 19 as a single phase material shows it to be a very promising compound to develop outstanding high-temperature permanent magnets. An ultrahigh intrinsic coercivity is achieved in a non-equilibrium compound stabilized over a wide temperature range by nanostructuring.
