The present paper concerns the production of dc magnetic materials by a PM route. The influence of compaction has been determined in the range 600–1000 MPa with a sintering range of 1450–1550 K and times of 2–24 h. The properties measured include magnetic permeability and coercive force. It is shown that, within the ranges studied, permeability and coercive force relate to density and structure, but resistivity induction and power loss are less affected. PM/0205
