The rare-ground-freematerial sciences invention relates to the field of permanent concerns-or soft magnets and corrosion resistant and, as they, for example, in motors, generators, loudspeakers or in devices for data storage or as holding magnets or for shielding of magnetic fields can be used. Is the purpose of the present invention, permanent magnets or soft magnets indicate rare-ground-free and corrosion resistant, and magnetically are stable even at higher temperatures the protected against oxidation are present. The problem is solved by permanent magnets or soft magnetsrare-ground-free and corrosion resistant, consisting of a non-magnetic and/or magnetic matrix and incorporated therein carbon nanotubes, with particles are filled in whole or in part from one or more Heusler compounds. The further problem is solved, by the use of carbon nanotubes, the with particles are filled in whole or in part from one or more Heusler compounds, and are embedded in a non-magnetic and/or magnetic matrix, as permanent magnets or soft magnets .
