This study presents a theoretical and experimental investigation of three distinct surface plasmon resonance (SPR) sensor configurations, evaluating their sensitivity and practical applications. The first configuration utilizes a commercially available SPR sensor, employing a coupling prism integrated with a thin gold layer in the well-established Kretschmann-Raether configuration for SPR excitation. The second configuration features an advanced design, incorporating a coupling prism combined with an optical multilayer structure and an additional magneto-optical layer, aimed at enhancing the sensor's response to magnetic fields and potentially broadening its application scope. The third configuration is a variation of the second, maintaining the optical multilayer but omitting the magneto-optical layer to assess its impact on sensor performance. Experimental results reveal that the third configuration exhibits the highest sensitivity among the three, making it a promising candidate for applications requiring precise detection capabilities.
