ABSTRACT:
The invention relates to a soft-magnetic material comprising a micro fraction composed of particles of a soft-magnetic material having a particle size in the range from 1 to 100 μm and a nano fraction composed of particles of a soft-magnetic material having a particle size in the range from 100 to 200 nm, where the proportion of the nano fraction based on the total mass of micro fraction and nano fraction is from 5 to 70% by mass and the particles of the micro fraction and the particles of the nano fraction optionally consist of the same material, and also a process for producing an article composed of the soft-magnetic material.
