The article investigates Co-(C-Pd) multilayer coatings produced by magnetron sputtering, focusing on their structure and magneto-optical behavior. Film thickness was controlled by the number of layers, and X-ray diffraction was used to analyze structural features. Magneto-optical properties were measured by the transmission line method. Impedance spectroscopy (50 Hz–100 MHz) showed decreasing phase angle at high frequencies, indicating dielectric losses. Charge accumulation was influenced by crystallite boundaries, bulk resistance, and surface effects. Very high ε′ and ε″ values were observed, with low-frequency growth explained by Maxwell–Wagner polarization. Frequency dependence of dielectric loss and conductivity confirmed electromagnetic absorption. Thicker multilayers demonstrated enhanced magneto-optical characteristics, underscoring the potential of Co-C-Pd coatings for spintronic and data-storage technologies.
