Abstract Soft magnetic compacted powder materials represent specific material class with expanding application range. They are intensively studied as there is still large potential for their properties improvement. The paper presents the innovative method of smoothing of surfaces of powder elements suitable for further compaction to create bulk materials exhibiting excellent magnetic properties. The positive impact of described method is documented by comparison of structure of compacts prepared from powders with and without smoothed surfaces. The measured results of magnetic properties – coercivity, total energy losses and complex permeability illustrate the positive effect of mechanical treatment on powder elements applied before pressing procedure.
