Abstract

The magnetic component uses at least two different layers of magnetic material for carrying and amplifying the magnetic flux. The use of two different layers which may, however, have the same material composition allows the magnetic conductors to form a magnetic circuit with a locally matched domain alignment. The magnetic component accordingly allows considerable improvements to be achieved in the component parameter, in particular a considerable increase in the Q-factor.
