ABSTRACT:
The composite material comprises an alternation of amorphous magnetic material films based on cobalt, niobium and zirconium and electrically insulating material films (4), each magnetic film being formed from several blocks (6) separated from one another by electrically insulating joints (8), the total volume (Vp) occupied by the magnetic blocks and the total volume (Vj) occupied by the insulating joints being such that the ratio (Vp/Vj) varies between 10 and 50. This material can be used in a wide range of applications with electromagnetic fields having a frequency between 50 MHz and several GHz.
