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.
