Abstract

Dense Mn-Al-C permanent magnets have been produced using melt-spinning and spark plasma sintering techniques. The samples have been magnetically characterized from 4 to 300 K in a field of up to 14 T. The ahysteretic parts of magnetization loops were analyzed within a model for the approach to saturation, which allows for possible crystallographic texture. The saturation magnetization and magnetocrystalline anisotropy energy have been determined considering the estimated fraction of ferromagnetic phase. The obtained magnetic parameters have been compared with the available theoretical and experimental data.
