Abstract
A method and system for the characterization of a magnetic element based on ferromagnetic resonance, the magnetic element presents ferromagnetic resonance and its own characteristic resonance frequency. The system includes mechanism for application of a low-frequency electromagnetic field in a given area; a mechanism for application of a high-frequency electromagnetic wave the same as the characteristic resonance frequency of the magnetic element in the same area; and a control unit configured so as to control the simultaneous application of the low-frequency electromagnetic field so that in response to the introduction of the magnetic element in the area the magnetic element absorbs the high-frequency electromagnetic wave with a frequency the same as that of the low-frequency electromagnetic field, so the wave is modulated. The system also comprises a mechanism for reception of this unique individual modulated wave characteristic of each element, and a mechanism for assignment of the unique modulated wave to the element.
