Abstract
Inductive microcomponent (1), such as a microinductor or microtransformer, comprising a metal winding (2) having the shape of a solenoid, and a magnetic core (4) including a strip made of a ferromagnetic material, positioned at the center of the solenoid (2), and characterized in that the core comprises at least one additional strip made of a ferromagnetic material (13), separated from the other strip (12) by a spacer layer (14) made of a non-magnetic material, the thickness of which is such that the strips (12, 13) located on either side of the spacer layer (14) are antiferromagnetically coupled.
