|Abstract:||Nanocrystalline hexaferrite (BaFe12O19 or SrFe12O19) and mixed Fe,Co-ferrite ((FexCo1-x)Fe2O4 with x=0-1) materials have been prepared by mechanical alloying and subsequent annealing. High coercivities were obtained in these nanocrystalline materials, 6-7 kOe for hexaferrite and ∼3 kOe for Co-ferrite. Hexaferrite powders prepared by mechanical alloying have been used as the starting material for high-coercivity bonded magnets. Hot-pressed anisotropic hexaferrite magnets have been produced with high values of coercivity and remanence. High magnetic performance was also achieved in some mixed Fe,Co-ferrites after magnetic annealing. © 1998 Elsevier Science S.A. All rights reserved.|
