The aim of the present paper is to report the results of a research conducted to investigate the possibility of application of magneto-optical cobalt based amorphous thin films as a magnetic field sensor. The sensing element is prepared by pulsed 6 6 laser deposition technique in one-dimensional magneto-photonic crystals with (TiO2/SiO2) / Co67Fe4B14.5 Si14.5/(SiO2/TiO2) structure. The optical and magneto-optical properties of the sample were studied in detail so as to use the hypotheses formulated to achieve good Faraday rotation of the media originating in the weak localization of light. Results indicate that Co-based amorphous thin films can be considered a candidate for use as a magnetic field sensor due to their efficient linearity behaviour with respect to the applied current.
