Abstract
Sm2TM17 magnets have been produced by powder metallurgical techniques, with TM standing for combinations of 3d transition metals. The compositional dependence as well as the influence of the different process parameters, as for instance particle size and sintering temperature, have been investigated. The maximum hard magnetic values obtained so far are a magnetic remanence of 11.3 kG and a coercivity field of 11 kOe. However, a maximum BR and IHc could not be obtained simultaneously so far. All the magnets present demagnetization curves typical for a chemically and structurally homogeneous compsition of the material. The hard magnetic properties observed are discussed with respect to the primary magnetic properties.
