    Abstract: The integrated microelectronics component comprises an electric conductor forming a transmission line element for a radio frequency electromagnetic wave. This electric conductor is surrounded at least partially by a preferably closed magnetic circuit, formed at least by superposition of a layer of ferromagnetic material having a saturation magnetization value greater than or equal to 800 kA/m and of a layer of magnetic material. The layer of magnetic material then generates a uniaxial magnetic anisotropy in the adjacent ferromagnetic layer. A high magnetization can then be combined with a high anisotropy, thus enabling operation in high frequency ranges, for example about 5 to 20 GHz.

    Abstract: The inductive micro-device comprises a rectilinear solenoid winding comprising a plurality of disjointed rectangular turns each having predetermined dimensions. At least one of the dimensions of the turns is variable and is determined individually for each turn according to the position of the turn along the winding and to predetermined magnetic characteristics of the winding, in particular a homogeneous magnetic field and/or an optimum quality factor. Said variable dimension of the turns is chosen from the width, length, thickness, height of turn and the value of the gap between two adjacent turns.
