Abstract (en)
A ferromagnetic composite body is produced by hot pressing a homogeneous mixture of a soft magnetic material powder and a glass-solder pressing aid which is viscous at the pressing temperature. A ferromagnetic composite body is produced by hot pressing a homogeneous mixture of a soft magnetic material powder and a glass-solder pressing aid which is viscous at the pressing temperature. An Independent claim is also included for a pressed ferromagnetic composite body produced by the above process. Preferred Features: The soft magnetic powder consists of rapidly solidified metallic glass especially with an Fe content of more than 70 at.%.
