Abstract:

In the present research, we have investigated the magneto-optical properties of Co-Zn ferrite thin films with different thicknesses of 60, 120, and 180 nm. The Faraday rotation angle for the thin films of ferrite—subjected to a continuous magnetic field parallel to the propagation direction of a laser beam—was measured. The results showed linear dependences of the Faraday rotation angle on the external magnetic field and film thicknesses. Our experimental results were completely in agreement with the theory: the Verdet constant was discovered to equal 4.58×10⁷ degrees/mT. In addition, the findings show promise for designing Faraday devices based on thin films.
